Imagination is the limit - as long as the sleds are cardboard and held together with tape or glue - no nails or staples allowed. The event starts with a parade to showcase the builders' talents, followed by the race. Each sled must have at least one rider. Cash prizes are awarded in three divisions: Best Box Decorated Like a Trail Name, Fastest Timed Run and Best Crash. There's plenty of entertainment for competitors and spectators alike with often surprising results. It's anyone's guess who will make it to the finish line – either first or in one piece.
