    v.
    Roger D. Zehm,
    Defendant-Appellant.
    Appeal from the United States District Court
    for the Western District of Wisconsin.
    No. 99-CR-1-S--John C. Shabaz, Chief Judge.
    Argued January 4, 2000--Decided June 27, 2000
    Before Cudahy, Kanne, and Diane P. Wood,
    Circuit Judges.
    Cudahy, Circuit Judge.
    I) Facts
    On January 6, 1999, a grand jury in the
    Western District of Wisconsin returned a
    four-count indictment against Roger Zehm,
    charging him with one count of conspiring
    with Trevor Christiansen to distribute
    methamphetamine from February 1998 until
    early April 1998 and one count of
    conspiring with Eric Brown to distribute
    methamphetamine from February 1998 until
    June 1998. Zehm was also charged with two
    counts of distributing methamphetamine--a
    total of 4.25 grams--to Cathy Lindstrom
    on April 29, 1998 and May 4, 1998. Police
    arrested Zehm on January 13, 1999.
    Pursuant to a plea agreement, Zehm
    pleaded guilty to counts 3 and 4, which
    involved the "retail" sales of
    methamphetamine. See Appellant’s Appendix
    B at 4. The trial court dismissed counts
    1 and 2, involving the Christiansen and
    Brown conspiracies, in which Zehm had
    allegedly made "bulk" purchases of
    methamphetamine and other drugs that he
    would subsequently sell to individual
    buyers.
    Zehm admitted he had been in the
    business of dealing drugs for twenty
    years. See Appellant’s Short Appendix at
    7 (Trial Court "Statement of Reasons").
    From the third week of February 1998
    until early April 1998, Zehm purchased
    methamphetamine and cocaine from Trevor
    Christiansen. He always paid in cash. As
    a rule, Zehm purchased drugs from
    Christiansen at Christiansen’s home.
    After making an initial quarter-ounce
    methamphetamine purchase from
    Christiansen, Zehm developed a routine in
    which he bought three-quarters of an
    ounce of methamphetamine every three days
    over a six-week period. Zehm purchased
    nine ounces of methamphetamine and one
    ounce of cocaine over the course of his
    relationship with Christiansen. From
    February 1998 until June 1998, Zehm also
    purchased methamphetamine from Eric
    Brown. Again, he began with a relatively
    small initial purchase (one ounce), and
    then developed a routine in which he
    bought two to four ounces of
    methamphetamine every other day. Zehm
    bought the drugs at Brown’s home in
    Minnesota, and always paid cash. During
    the month of May 1998, Brown was
    imprisoned. Scott Wells, who supplied
    Brown with methamphetamine, sold directly
    to Zehm on Brown’s behalf while Brown was
    incarcerated. According to the
    Presentence Investigation Report, Zehm
    purchased 81 ounces total from Brown and
    Wells. The district court explained that
    Zehm maintained multiple drug suppliers
    so that he would have a ready source of
    drugs even if a supplier occasionally was
    unavailable.
    During the period Zehm was buying "bulk"
    quantities of methamphetamine from Brown,
    Wells and Christiansen, he was
    distributing the methamphetamine to
    individual drug users. Zehm lived in
    space adjacent to an auto repair shop
    owned by Joel Berg, and his rent payments
    consisted of methamphetamine rather than
    money. Russell Mork, a steady one-ounce
    per month customer of Zehm’s, cooperated
    with the government after Zehm’s arrest.
    He told the grand jury that he saw Zehm
    distribute methamphetamine to five
    people, and said he had been told that
    Zehm had been selling a quarter pound of
    methamphetamine every day for a month and
    a half. See Appellant’s Appendix at 75
    (Gov’t Response to Presentence
    Investigation Report, Attachment C, at
    1).
    In March 1998, while Brown and
    Christiansen were serving as two of
    Zehm’s steady suppliers, Zehm met Cathy
    Lindstrom at a party. Lindstrom became a
    steady half-gram per week customer of
    Zehm’s. In April 1998, police arrested
    Lindstrom for marijuana possession with
    intent to distribute. She cooperated with
    authorities, and made two controlled
    methamphetamine purchases from Zehm on
    April 29 and May 4. Zehm had purchased
    the methamphetamine sold to Lindstrom
    from a third supplier, Jeremy Baker.
    On May 8, 1998, police executed a search
    warrant on Zehm’s car. They found 14.6
    grams of cocaine, 1.2 grams of
    methamphetamine, a loaded .32 caliber
    derringer, records of his drug sales to
    various individuals, $4,000 in cash and a
    cellular phone. Several of Zehm’s
    customers, as well as Eric Brown and
    Trevor Christiansen, testified before the
    grand jury about Zehm’s drug business.
    They furnished details about the quantity
    of Zehm’s purchases and sales. The trial
    court relied on these statements in
    determining Zehm’s sentence.
    The trial court sentenced Zehm to two
    240-month terms of imprisonment, running
    concurrently. In determining the
    sentence, the court included as relevant
    conduct the 4.25 grams of methamphetamine
    Zehm sold to Lindstrom on April 29 and
    May 8, to which Zehm had pleaded guilty.
    The court also included in Zehm’s
    relevant conduct his "bulk"
    methamphetamine purchases from Brown,
    Wells and Christiansen, even though Zehm
    had not pleaded guilty to those counts.
    The court determined that the bulk
    purchases amounted to 90 ounces of
    methamphetamine. Zehm contends on appeal
    that these purchases should not be
    included as relevant conduct.
    Additionally, he argues that even if the
    trial court was entitled to account for
    his purchase from Brown and Christiansen,
    it miscalculated the total amount
    purchased by 75 ounces because it
    erroneously credited Brown’s unreliable
    testimony. The trial court also denied
    Zehm’s request for a three-level
    reduction for acceptance of
    responsibility. Zehm protests this
    denial. Finally, the trial court also
    determined that the loaded gun found in
    Zehm’s car warranted a two-level
    sentencing adjustment because Zehm
    possessed it during the commission of a
    drug offense. Zehm challenges these
    conclusions.
    II) Analysis
    A) Relevant Conduct
    The Sentencing Guidelines instruct that
    a defendant’s base offense level reflect
    the quantity of drugs for which the
    defendant is accountable. See United
    States v. Griffin, 
    194 F.3d 808
    , 826 (7th
    Cir. 1999), citing U.S.S.G. sec. 2D1.1.
    The base offense level must reflect not
    just the amount of drugs involved in the
    offense of conviction, but also the
    defendant’s "acts and omissions . . .
    that were part of the same course of
    conduct or common scheme or plan as the
    offense of conviction." U.S.S.G. sec.
    1B1.3(a)(2). We review for clear error
    the district court’s application of the
    so-called "aggregation rule" to determine
    drug quantities attributable to relevant
    conduct, including both convicted and
    unconvicted offenses. See United States
    v. Bacallao, 
    149 F.3d 717
    , 719 (7th Cir.
    1998). The government has a significantly
    lighter burden at sentencing than it had
    at trial, because it need only prove
    relevant conduct by a preponderance of
    the evidence, and relaxed evidentiary
    rules apply. See United States v.
    Crockett, 
    82 F.3d 722
    , 729 (7th Cir.
    1996). As a measure of restraint,
    however, we insist that sentencing courts
    "explicitly state and support, either at
    the sentencing hearing or (preferably) in
    a written statement of reasons, the
    finding that the unconvicted activities
    bore the necessary relation to the
    convicted offense." See United States v.
    Beler, 
    20 F.3d 1428
    , 1432 (7th Cir.
    1994), citing United States v. Duarte,
    
    950 F.2d 1255
    , 1263 (7th Cir. 1991).
    The government may prove the necessary
    link between the convicted and
    unconvicted offenses in two ways. It may
    argue that the offenses are part of a
    "common scheme or plan." U.S.S.G. sec.
    1B1.3(a)(2). Or it may contend that the
    offenses are part of the same "course of
    conduct." 
    Id. While these
    two
    formulations sound similar, they actually
    capture two distinct concepts. Offenses
    are part of a common scheme or plan if
    they are connected by at least one common
    factor, such as "common victims, common
    accomplices, common purpose, or similar
    modus operandi." See 
    Bacallao, 149 F.3d at 719
    , citing U.S.S.G. sec. 1B1.3(a)(2),
    Application Note 9. Offenses are part of
    the same course of conduct if they are
    "part of a single episode, spree, or
    ongoing series of offenses." 
    Id. Courts assessing
    whether offenses are part of a
    course of conduct focus on whether the
    offenses were similar, regular, and close
    in time. See 
    Bacallao, 149 F.3d at 719
    .
    In the present case, the trial court
    provided, as required by Beler, a written
    statement of reasons, in which it
    explicitly identified the basis for its
    finding that the unconvicted counts of
    bulk drug purchases from Christiansen and
    Brown were relevant conduct. See
    Appellant’s Short Appendix at 7
    (Statement of Reasons). It expounded on
    its reasoning at sentencing. See
    Sentencing Transcript at 19-20. The trial
    court found that the unconvicted drug
    purchases met both tests for relevant
    conduct. "Having multiple sources for his
    drugs he turned from Christiansen to
    Brown to Wells. His purpose remained the
    same--to secure drugs for himself and his
    customers . . . . Although defendant was
    not convicted of counts 1 and 2, the
    conduct embodied therein is included in
    the guideline computations because it was
    part of the same course of conduct or
    common scheme or plan as the offenses of
    conviction . . . ." Short Appendix at 7
    (Statement of Reasons).
    Though it purported to find both a
    common scheme and a course of conduct,
    the trial court’s written explanation
    identified just one relevant conduct
    factor, the common purpose driving the
    unconvicted drug purchases and the
    convicted drug sales. In its oral
    statement, the court identified the
    similar modus operandi throughout the
    period in question. Common purpose and
    similar modus operandi are factors
    suggesting a common scheme. Therefore, we
    will first review whether the trial court
    erred in finding that Zehm’s offenses
    were part of a common scheme or plan. As
    the district court stated, Zehm admitted
    to having dealt drugs for two decades.
    Zehm appears to have been the
    quintessential middleman--purchasing
    wares in bulk from suppliers, and selling
    them in retail quantities to individuals.
    Such "dealing" necessarily requires that
    the dealer both buy and sell drugs. Zehm
    could not, in other words, have completed
    the retail sales for which he was
    convicted without first acquiring drugs
    from a supplier. The trial court’s brief
    explanation captured this essential
    reality when it referred to Zehm’s
    sellers as drug "sources" and, in turn,
    to his drug "customers." Courts have
    recognized that purchases predating
    convicted sales may be considered
    relevant conduct. For instance, in United
    States v. Vital, 
    68 F.3d 114
    , 116 (5th
    Cir. 1995), the defendant was convicted
    of one count of possession with intent to
    distribute cocaine, after he sold 27.7
    grams of cocaine to an undercover police
    officer. The Fifth Circuit let stand the
    trial court’s decision to include as
    relevant conduct the convicted sale, a
    subsequent sale to the same officer one
    week later, and thrice-weekly purchases
    of cocaine made on the defendant’s behalf
    in the month preceding the convicted
    sale. See 
    id. at 116-18.
    In the case now before us, Zehm admitted
    to a two-decade career as a drug dealer.
    Throughout the period in question, he had
    regular customers who scheduled routine
    drug purchases and therefore he could
    calculate the inventory required to meet
    demand. Cathy Lindstrom, whose two
    purchases gave rise to Zehm’s conviction,
    purchased a half gram of methamphetamine
    from Zehm weekly. Russell Mork purchased
    one ounce of methamphetamine from Zehm
    every month, and testified that Zehm had
    been selling a quarter pound of
    methamphetamine daily for the six weeks
    prior to his arrest. Zehm even made his
    monthly rent payments in methamphetamine.
    This steady, predictable demand was
    fueled by a steady, predictable supply
    from Christiansen and Brown (and Brown’s
    stand-in, Wells). Zehm purchased three-
    quarters of an ounce of methamphetamine
    every three days from Christiansen, and
    two to four ounces of methamphetamine
    every other day from Brown. The routine
    weekly sales to Lindstrom would not have
    been possible, in light of the high
    demand for Zehm’s product, without the
    steady, reliable supply provided by
    Christiansen and Brown./1 Thus, a
    common purpose--maintenance of a high-
    volume drug distributorship--propelled
    both the convicted retail sales and the
    unconvicted bulk purchases. Further, as
    the sentencing court noted, Zehm’s modus
    operandi throughout the relevant time
    period was similar. He drove to the homes
    of his suppliers on a predictable,
    frequent schedule and paid in cash for
    small, fixed amounts of drugs. He then
    sold the drugs in regular quantities to
    repeat customers. Based on these two
    factors--commonality of purpose and
    similarity of modus operandi--the trial
    court did not clearly err in counting the
    purchases from Christiansen and Brown in
    Zehm’s relevant conduct.
    The trial court also concluded that the
    evidence was sufficient to prove that all
    the offenses were part of a course of
    conduct. The court’s written explanation
    does not identify any factors supporting
    this conclusion. But at the sentencing
    hearing, the judge stated that "[h]e
    purchased methamphetamine from
    Christiansen, Brown, and then he resold
    the methamphetamine. All of this was the
    same course of conduct. . . . He
    purchased it from suppliers, whether it
    be Christiansen or whether it be Brown or
    whether it be a subsequent supplier.
    There was regularity, proximity between
    the counts of conviction and his
    methamphetamine dealing with Christiansen
    and Brown." Sentencing Tr. at 19. A
    course of conduct involves an ongoing
    series of offenses, and courts are to
    examine whether the offenses were
    similar, regular and close in time. See
    
    Bacallao, 149 F.3d at 719
    . For instance,
    in United States v. Benitez, 
    92 F.3d 528
    (7th Cir. 1996), we affirmed the trial
    court’s finding that the defendant had
    engaged in a "course of conduct"
    goingbeyond the offense of conviction;
    this extended conduct involved a four-
    kilogram cocaine purchase from a
    confidential informant. See 
    id. at 539.
    During the two years the informant was in
    touch with the defendant, she had
    frequently discussed the demand for
    cocaine and the corresponding police
    surveillance of suspected drug dealers.
    See 
    id. at 531-32.
    In addition to several
    stray remarks regarding her cocaine
    dealing, the defendant on one occasion
    remarked that she had seven kilograms of
    cocaine in her possession, and at another
    time estimated that she could sell up to
    eight kilograms in the near future. See
    
    id. at 537,
    539. We concluded that the
    defendant’s ability to calibrate her
    cocaine purchases and likely cocaine
    sales indicated that the convicted
    purchase was part of a course of drug-
    dealing conduct. See 
    id. at 538.
    We
    affirmed, finding that the defendant’s
    revelations to the informant demonstrated
    a course of conduct involving at least
    five kilograms of drugs. See 
    id. at 538-
    39. Similarly, in United States v.
    Townsend, 
    73 F.3d 747
    , 749 (7th Cir.
    1996), a defendant pleaded guilty only to
    one count of drug possession. But the
    sentencing court heard evidence that he
    had been making biweekly drug deliveries
    to two distributors for the six months
    leading up to his possession offense, and
    we affirmed that the drug deliveries were
    sufficiently regular to amount to a
    course of conduct consistent with his
    possession conviction. See 
    Townsend, 73 F.3d at 752
    .
    Based on these precedents, we agree with
    the trial court that Zehm’s drug
    purchases and drug sales were an ongoing
    series of offenses. Though buying and
    selling are, in a sense, dissimilar
    activities, they are structurally
    symbiotic. As in Benitez, we recognize
    that a mid-level drug dealer who
    simultaneously estimates impending demand
    and tries to procure an adequate supply
    is engaged in a course of conduct. One
    cannot sell drugs one has not procured.
    Further, the trial court in the present
    case correctly zeroed in on the
    regularity of Zehm’s buys. He purchased
    every other day from Brown, and every
    third day from Christiansen. He routinely
    went to their homes to buy drugs, and
    always paid in cash. He sold drugs once a
    week to Lindstrom, once a month to Mork,
    and paid his rent in drugs, in addition
    to servicing other customers who
    apparently purchased a quarter-pound of
    methamphetamine daily. This metronomic
    scheduling is similar to the biweekly
    sales found regular in Townsend. Finally,
    the acts in this ongoing series of
    offenses were not just close in time, but
    virtually simultaneous. The relevant time
    period was February 1998 to June 1998;
    during that time Zehm bought drugs on
    alternating days from Brown and
    Christiansen, and from March to April,
    was selling drugs to Lindstrom. Though
    the trial court did not explicitly cite
    these facts when concluding that Zehm
    engaged in a course of conduct, the
    record amply supports that finding. In
    sum, the trial court did not commit clear
    error in finding that Zehm’s relevant
    conduct included the unconvicted
    Christiansen and Brown drug conspiracies.
    Zehm protests the district judge’s
    relevant conduct calculation on an
    additional ground. Even if the sentencing
    court was correct to include the Brown
    conspiracy, he argues, the court
    incorrectly calculated the drug quantity
    attributable to that conspiracy. The
    trial court determined that Zehm was
    responsible for 2.55 kilograms of metham
    phetamine, leading to a base offense
    level of 34 (reflecting responsibility
    for between 1.5 and 5 kilograms of
    drugs). Zehm admitted that he purchased
    nine ounces of methamphetamine from
    Christiansen. Additionally, the trial
    court found that Zehm purchased 81 ounces
    of methamphetamine in the course of the
    Brown conspiracy. Zehm counters that he
    purchased just six ounces from Brown.
    Again, we review the trial court’s
    relevant conduct calculation for clear
    error. See 
    Griffin, 194 F.3d at 827
    .
    Zehm argues that the sentencing court
    erred by crediting Brown’s allegedly
    unreliable testimony in order to arrive
    at the 81-ounce figure. Brown testified
    that he began dealing with Zehm in March
    1998 and continued dealing with him until
    June 1998. Further, Lindstrom, Neely and
    Mork appeared to corroborate that Eric
    Brown was supplying large amounts of
    methamphetamine to Zehm on a regular
    basis. One witness reported that Zehm had
    been purchasing between $4,000 and $8,000
    of methamphetamine regularly "from his
    source, Eric, in Little Canada,
    Minnesota." Presentence Investigation
    Report at par. 15. Further, even after
    supplier Christiansen’s April arrest,
    witnesses stated that Zehm continued to
    have access to large quantities of drugs,
    suggesting that he had found an alternate
    supplier. Indeed, one witness stated that
    "Roger Zehm is getting [drugs] from Eric
    Brown as his source after Christiansen
    was arrested." Appellee’s Br. at 23.
    Zehm assails this evidence on many
    grounds. He argues that Brown is not a
    reliable witness because as the primary
    drug supplier in the alleged conspiracy,
    "he has the greatest incentive to
    fabricate." Appellant’s Br. at 21. This
    fabrication is evidenced, he argues, by
    the fact that Brown did not specifically
    state that he stopped dealing drugs to
    Zehm either while Zehm was jailed from
    May 6 to May 20, or when Brown was jailed
    from late May to June 12. It is axiomatic
    that the defendant has a due process
    right to be sentenced on the basis of
    reliable information. See United States
    v. Lanterman, 
    76 F.3d 158
    , 160 (7th Cir.
    1996). But we have stated that the
    hallmark of reliability is consistency of
    facts and details. See United States v.
    Galbraith, 
    200 F.3d 1006
    , 1012 (7th Cir.
    2000) (collecting cases). The testimony
    of just one witness, even a potentially
    biased witness, is sufficient to support
    a finding of fact. See 
    Galbraith, 200 F.3d at 1012
    , citing United States v.
    Cedano-Rojas, 
    999 F.2d 1175
    , 1180 (7th
    Cir. 1993). We require only that the
    testimony be consistent, or that the
    trial judge provide an explanation for
    crediting one of the witness’s
    inconsistent statements over the others.
    See 
    Galbraith, 200 F.3d at 1013
    . For
    instance, when witnesses have given
    varying estimates of the amount of drugs
    they sold or purchased, we have not
    permitted the trial judge to credit one
    of the amounts without explaining why it
    was more believable than the others. See,
    e.g., United States v. McEntire, 
    153 F.3d 424
    , 436 (7th Cir. 1998); 
    Beler, 20 F.3d at 1430-33
    .
    In the present case, Brown’s status as
    a government witness and alleged drug
    dealer does not sufficiently import bias
    so as to undermine the reliability of his
    testimony. Further, the "inconsistencies"
    Zehm targets are of no moment. The
    Presentence Investigation Report flatly
    contradicts Zehm’s suggestion that Brown
    did not admit he ceased dealing drugs to
    Zehm during Brown’s incarceration. It
    reports that "Brown stated that Graig
    Wells took over his business while he was
    in jail and started dealing to [Zehm]."
    Presentence Investigation Report at 6,
    par. 23. And while Brown did not
    specifically detail the two-week break in
    his dealing to Zehm while Zehm was in
    jail, he also did not explicitly state
    that he dealt drugs to Zehm during the
    period in question. Thus, Brown’s account
    is not overtly inconsistent with reality.
    Zehm also charges that Brown incorrectly
    stated he began dealing with Zehm in
    March 1998, while one witness stated that
    "Zehm is getting methamphetamine from
    Eric Brown as his source after
    Christiansen was arrested [in April]."
    Again, this statement is subject to
    interpretation. It could well have meant
    that although Brown was initially a minor
    supplier to Zehm, he expanded his role
    when Christiansen suspended business upon
    his arrest. In short, nothing said by
    Brown or witnesses corroborating his
    account was at odds with other witnesses,
    or with Zehm’s version of events, and
    therefore we do not believe that Brown’s
    testimony should be characterized as
    unreliable. The trial judge did not
    clearly err in crediting Brown’s
    testimony or in calculating that Zehm had
    purchased 81 ounces of methamphetamine
    from Brown. We therefore affirm the trial
    court’s relevant conduct calculation in
    its entirety.
    B) Acceptance of Responsibility
    Zehm asked the sentencing judge to
    decrease his sentence to reflect that he
    had accepted responsibility for his
    crimes, pursuant to U.S.S.G. sec. 3E1.1.
    That section provides that a defendant
    whose offense level is on par with
    Zehm’s, and who "clearly demonstrates
    acceptance of responsibility for his
    offense" should receive a three-point
    decrease in his offense level. The
    commentary to this provision advises
    sentencing judges that they may consider
    factors such as
    truthfully admitting the conduct
    comprising the offense(s) of conviction,
    and truthfully admitting or not falsely
    denying any additional relevant conduct
    for which the defendant is accountable
    under sec. 1B1.3. . . . A defendant is
    not required to volunteer, or
    affirmatively admit, relevant conduct
    beyond the offense of conviction in order
    to obtain a reduction under subsection
    (a). A defendant may remain silent in
    respect to relevant conduct beyond the
    offense of conviction without affecting
    his ability to obtain a reduction under
    this subsection. However, a defendant who
    falsely denies, or frivolously contests,
    relevant conduct that the court
    determines to be true has acted in a
    manner inconsistent with acceptance of
    responsibility.
    U.S.S.G. sec. 1B1.3, Application Note
    1(a).
    The judge denied the reduction, based on
    Zehm’s challenge to the relevant conduct
    calculations. Zehm appeals this denial.
    We review for clear error a sentencing
    court’s factual determination of whether
    a defendant has accepted responsibility.
    See United States v. Herrera-Ordones, 
    190 F.3d 504
    , 511 (7th Cir. 1999); United
    States v. Taylor, 
    72 F.3d 533
    , 550 (7th
    Cir. 1995).
    We have previously withheld the
    acceptance of responsibility deduction
    from defendants who deny relevant conduct
    in the face of sworn statements from
    witnesses or coconspirators tying them to
    the offenses in question. For instance,
    in 
    Taylor, 72 F.3d at 547-49
    , the
    sentencing court computed relevant
    conduct based on the Presentence
    Investigation Report. That report, in
    turn, relied on statements from "at least
    half a dozen individuals with first-hand
    knowledge of the drug-distribution
    network . . . who . . . gave largely
    consistent and mutually-corroborating
    accounts . . . [but] provided varying
    estimates of drug quantities." See 
    id. at 543.
    The defendant challenged the
    relevant conduct calculation, denying the
    statements of witnesses and contesting
    the sentencing judge’s application of the
    aggregation rule. The court subsequently
    denied the defendant a reduction for
    acceptance of responsibility, stating
    that while it is "perfectly appropriate"
    for a defendant to contest the amount of
    drugs, it was inappropriate to "deny
    frivolously" the extent of involvement in
    the conspiracy. 
    Id. at 550.
    Because the
    defendant’s story was wholly at odds with
    the statements of witnesses, the judge
    concluded that her denial was false and
    the reduction unwarranted.
    Zehm’s case squares exactly with Taylor.
    Zehm contested the judge’s application of
    the aggregation rule, and denied
    responsibility for the full extent of his
    involvement in the Brown conspiracy in a
    statement wholly at odds with witness
    testimony. The sentencing court explained
    that the defendant had "falsely denied
    and frivolously contested relevant
    conduct which the Court has determined to
    be true," and therefore did not merit a
    sentence reduction. Zehm now argues that
    he never denied his part in the Brown or
    Christiansen conspiracies, but merely
    challenged whether they were relevant to
    the offense of conviction. Had he
    restricted himself to such legal
    maneuvering, we might take a more
    favorable view of this matter. But he
    also challenged the amount of drugs
    attributable to the Brown conspiracy. As
    in Taylor, he offered only his bare
    denials to counter the largely consistent
    stories of several witnesses. The
    sentencing court did not clearly err in
    finding that Zehm’s challenge was
    frivolous, and we therefore affirm its
    decision to deny the sentence reduction.
    C) Possession of Dangerous Weapon
    On May 8, 1998, four days after Zehm
    completed a controlled sale of
    methamphetamine to Lindstrom, a confiden
    tial informant told police that Zehm
    would be picking up about $8,000 worth of
    methamphetamine that evening. Police
    intercepted Zehm that night, and stopped
    his car. He denied police permission to
    search the car, but police obtained a
    warrant over the phone. They searched the
    car and found cocaine and
    methamphetamine, drug paraphernalia,
    $4,000 in cash and a .32 caliber gun with
    two live rounds of ammunition.
    The district court explained in its
    written Statement of Reasons that it
    added two points to Zehm’s base offense
    level because section 2D1.1(b)(1) of the
    Sentencing Guidelines requires an
    adjustment for possession of a firearm
    during an offense. Commentary to the
    provision states that "[t]he adjustment
    should be applied if the weapon was
    present, unless it is clearly improbable
    that the weapon was connected with the
    offense." Application Note 3. Section
    2D1.1(b)(1) requires active or
    constructive possession of a firearm. See
    United States v. Griffin, 
    150 F.3d 778
    ,
    786 (7th Cir. 1998), citing United States
    v. Wetwattana, 
    94 F.3d 280
    , 283 (7th Cir.
    1996). Constructive possession exists
    when a person exercises control over the
    firearm. See 
    Wetwattana, 94 F.3d at 283
    .
    For instance, a defendant who sat in the
    back seat of a car next to a gun
    concealed in a tissue box was held to
    have possessed the gun. See 
    id. And when
    police impounded a car and found drugs in
    the cargo area and a gun concealed in a
    briefcase on the floor of the front
    passenger seat, we held that the
    defendant possessed the gun in connection
    with the drug offense. See 
    Griffin, 150 F.3d at 786
    . Further, a defendant need
    not possess the gun during the offense of
    conviction, but may possess it during
    relevant conduct. See 
    Wetwattana, 94 F.3d at 283
    , citing United States v. Anderson,
    
    61 F.3d 1290
    , 1303-04. Thus, in United
    States v. Mumford, 
    25 F.3d 461
    , 468 (7th
    Cir. 1994), we affirmed a weapons
    enhancement for a defendant whose
    coconspirator carried a gun not during
    the transaction for which the defendant
    was convicted, but during other
    transactions considered to be relevant
    conduct. See also United States v. Price,
    
    54 F.3d 342
    , 348 (7th Cir. 1995). We
    review the district court’s upward
    adjustment of a sentence for clear error.
    See 
    Wetwattana, 94 F.3d at 283
    .
    The relevant conduct period in Zehm’s
    case extended from February 1 until June
    30. The Christiansen conspiracy ended on
    April 7, when Christiansen was arrested,
    but the Brown conspiracy continued. Thus,
    the Brown conspiracy was ongoing on May
    8, the date the defendant was found to be
    in possession of the weapon. Moreover,
    the gun was found in close proximity to
    drugs, lending credibility to the trial
    court’s determination that it was not
    clearly improbable the gun was possessed
    in connection with the drug offense. See
    Sentencing Tr. at 26. Further, according
    to the report of a confidential
    informant, Zehm was retrieving drugs from
    Minnesota when police searched his car
    and found the gun. Thus, as in Mumford,
    Zehm did possess the gun during the Brown
    conspiracy even though he may not have
    possessed it during the convicted sales
    to Cathy Lindstrom. The trial court did
    not clearly err in finding that Zehm
    possessed the gun during conduct relevant
    to the convicted offenses, and we affirm
    its decision to enhance Zehm’s base
    offense level by two.
    III) Conclusion
    The trial court correctly analyzed and
    explained that Zehm engaged in the
    unconvicted conspiracy offenses as part
    of a scheme or plan and as part of a
    course of conduct common with the
    convicted drug sales. The trial court
    correctly found Brown’s testimony
    reliable and rightly computed the amount
    of drugs attributable to Zehm as a result
    of the Brown conspiracy. The court did
    not err by denying Zehm an acceptance of
    responsibility deduction, because it
    soundly determined that Zehm had
    frivolously contested the extent of his
    relevant conduct. Finally, the trial
    court properly enhanced Zehm’s sentence
    by two levels to reflect the fact that he
    possessed a firearm during conduct
    relevant to the convicted offenses. We
    affirm on all grounds.
    /1 Zehm contends that the methamphetamine he sold
    to Lindstrom in the convicted offenses was
    actually purchased from a third supplier, Jeremy
    Baker. Thus, neither Christiansen nor Brown was
    linked to the convicted sales, he argues. The
    provenance of Lindstrom’s methamphetamine on the
    charged occasions is irrelevant. Zehm worked with
    several suppliers in order to satisfy demand in
    the Polk County, Wisconsin, area. Had he not
    dealt with Christiansen or Brown, the drugs he
    purchased from Baker might have been insufficient
    to cover all of his customers, including
    Lindstrom. So the Christiansen and Brown
    conspiracies were essential to the completion of
    the convicted sales to Lindstrom.
