Our preteen team had a booth. Kids were challenged to use a straw to blow a paper ball across a U.S. map to a designated state. Depending on how many tries it took, they won everything from a Bible Express magazine to posters of Christian artists to CDs of Leeland, Michael W. Smith, John Waller, Third Day, Casting Crowns, Brandon Heath, and more.
After work, I went and got a drug test. It seemed almost everyone was there for a drug test. Imagnine six to eight people spread out all over the waiting room... everyone chugging a bottle of water. ;)
