For what it's worth, my observations on learning to snowboard as an adult...
OK, a little background: I learned to snowboard a few years ago, I was 33. I've since learned to surf, and I've messed with a skateboard (I suck). I haven't done any skiing since I was 13 or so, but while learning to snowboard I was with friends who were intermediate skiers so it was easy to judge my progress against them.
First off: Use a Helmet and wrist guards! You are going to fall about a billion times, most of the times backwards on your wrists, sometimes hurling backwards and hitting your head.
Snowboarding has a brutal learning curve for the first three days (compared to skiing), then it becomes much easier. I was told this by all the instructors and it is certainly what I experienced. Just getting around on a snowboard (which you do by unlatching one foot) is awkward. It's crazy, you can't even walk, much less board. You're going to want to get through this stage as fast as possible so take classes, don't just flail around on the slope by yourself. My skier friends spent this time on the slope, having fun, laughing at me.
After five or six days I was hanging with my intermediate skier friends. They were waiting for me a lot but I was out there with them.
At ten days I wait for them. Slow wussies.
This happened in three trips over the course of two years (two days, four days, four days).
Some miscellaneous observations:
- I've had people tell me one board sport (snowboard/surfboard/skateboard) is just like another, but I can't see it. Sure they all train your balance which is helpful, but other than that they all feel different to me. So don't let the fact that you suck on a skateboard dissuade you. I suck on them also
- Since Snowboarding (once over that initial hump) is easier than skiing it's perfect for those who only go every now and then: you'll be able to do more trails with less skill. When I talk with people who live in Tahoe (where I learned) they usually both ski and snowboard, and just pick the one that best suits them on any given day.
- Moving across a flat surface or incline sucks with a snowboard. Many times I've miscalculated (or just fell down) on a flat part of a slope and had to have a skier friend pull me. Those polls they have are useful.
- My skier friends fall like once a day, at the end, when they're tired and take it as a signal that it's time to end the day. I fall constantly and spectacularly. I think that’s because you get so much better every day when first learning to board that you’re constantly pushing into new territory.
So I'd say to anyone give it a shot and have fun! Know that you're going to have to be patient for a few days. Unless you're not going to wear the wrist guards and helmet, then don't do it.
