Or perhaps, could it be an incompatible style of usage of the slopes e.g. on AVERAGE the very nature of snowboards encourage a style of sliding down the hill that is dangerous to other users. As the too many people who engage in this encouraged dangerous style of sliding down the hill can’t be discerned from the responsible boarders, those that don’t fall for the lure of dangerous sliding down the hill, the only way to make the slopes less dangerous is to ban all boards. Hmmmm…. the same reason that discs, tubes and sleds aren’t allowed on the ski slopes. Go figure.

Just because you want to use something your particular way, doesn’t mean its your right to do so. I would suggest those snowboarders get skis if they want to enjoy Alta.

Understood, but does it then matter whether Alta is a government business or a private business?
