The Cardboard Classic is an event held at Jack Frost Mountain every year. It’s hosted by the Preston and Steve Show on 93.3 WMMR in Philadelphia. Their listeners are challenged to create the craziest, biggest, outlandish sled they can out of cardboard and race them down the mountain to see if they can hold up and the results are incredible. Some prizes are given out in form of a cardboard trophy for fastest sled, best design and greatest fail.
