I tried boarding for the first time last season, I did get hurt becuase I tried to twist out of my bindings (unconcious natural reaction) and fell down crooked. I still had fun and will try it again sometime. It seems like a nice distractions from skiing if I ever get bored or if I want to spend time with people who are new to either boarding or skiing.
I don't know if safety release ski bindings would have become the norm if current liability concerns had existed back then.
Safety release bindings have been available to telemarkers for years. Can't blame the lawyers for lack of interest. Freeheel skiers are just dumb. No, no, wait, it's because we ski in places where a release would be fatal, better to pop a ligament than die.
