Snowboarding is cool i think. i just got a chance to hit some absolutely diabolical slopes in Colorado, they were hard for me since i'm a total beginner but it was a hell of a time and i'd recommend it to anyone who has the cash and time/location to do it. It burns the hell out of your muscles though, i was sore for like a week straight the last time i went. maybe try skiing first though if you're totally new.
