The Preston & Steve Show, a popular radio show in Philadelphia, hosts an annual Cardboard Classic at Jack Frost Mountain. Basically, the event is a contest where people build “sleds” with different themes out of cardboard, tape, glue, string, and paint, then they ride down one of the snow covered mountains. Prizes are given away for best sled, best time, etc. Each sled is designed with any theme the builders desire. This year, a Ghostbusters Stay Puft Marshmallow Man sled was submitted and it won for best sled.
