Although it's hard to get at first, the feeling of carving down some fresh powder for the first time ever is totally unmatched. You really feel connected to nature, too. Cons: Steep learning curve, expensive equipment. Just remember to fall 7 times, and get up 8!
Probably the best sport in the world once you learn 2 do it, the freedom of an open slope is amazing Cons: Expensive, takes a while to learn, sore butt when your learning, NOT for people afraid of speed/big slopes/cold weather
You look cool if you know what you're doing; nice alternative to skiing; freeing in a way Cons: Since both legs are secured to the one board, it can be very dangerous and painful when you fall; make sure you take a lesson before attempting the first time!
