jason harvey, in the video above, might be the world's first professional trampoline skateboarder. he is also the inventor of the "tramp trucks", which can be fixed on any regular skateboard deck, which enables you to "skate" on a trampoline.
personally, i think this is an ingenious idea/invention that can improve ones aerial and varial skills on a normal skateboard. but the only down side about tramp skating, is the adrenaline rush when one pushes a skateboard (with regular trucks and wheels) and cruise. 'nuff said, watch the video above and enjoy!
oh yeah, in case y'all are wondering, jason harvey also rides a real skateboard.
check out the tramp skate company.
