Snowskate Lib Tech Snowboards
whatever. as long as the lifts will let you on and its not going to drop on someones head on the way up, or kill someone on the way down, ride it.
there was a dude at my local hill with a skate deck on 3" standoffs on top of a wide ski. No straps. He rode it well, even had a little tether to keep it from flying off his leg. pretty fun watching him...just waiting for that moment when the speed got too scary and he would bail, but he took it down a steeper green circle slope going about 20 mph...
