<------- scratches "learning to snowboard" off the "Things to try" list.
I broke my arm and my wrist the first (and last) day I tried to snowboard. This is after having skied for 10+ years.
Nobody told me you aren't supposed to stick your arms out to break your fall when you are going face-first into the slope. It probably also would have helped if I hadn't gone up the lift to a black diamond on my first ever run down the mountain...
