It freakin' Mezmerizing!!

This is a whole other animal. Surfers love them. They're heavy, have adjustable air pneumatic tires, and the deck tilts off springs so you can carve insanely tight angles. I use one with tires deflated to about 10 lbs. pressure to be able to skate a steep local hill that I can't handle on any other board.
