Charlie and Bridget Capper, left, race Levi and Dallas Hill during the annual Cardboard Classic Bobsled Races held Saturday at The Chiller ice skating rink. The 6th annual event was sponsored by the National Trail Parks and Recreation District. Teams of families and friends pushed the sleds, all made of cardboard, tape, glue with a pilot on board, down the ice. The teams raced against each other and the clock for prizes. BILL LACKEY/STAFF
