Ah, those good old zero consequence airbags. A few years ago when copper first installed theirs, a lifty decided he would have a huck, and jacked the shit out of his back. I never did find out if he made it back to work that season.
My personal worst injury on a snowboard happened in Woodward at coppers foam-pit - I almost broke my neck, my buddy also blew out his knee landing in that foam-pit pretty soon afterwards.
At the end of the day do whatever you want, its snowboarding, its awesome, and its dangerous. Just don't think that anything is zero consequence. Less consequence maybe, but you're going to want to take it to snow at some point anyway - so why not build that progression on the snow. I learned back 3's on sidehits on a catroad going almost at a standstill.
