I looooove skiing high. I'm into backcountry steeps and deep powder, so I just roll with the fall lines and carve nice turns. I'll limit my smoking if I'm at a crowded area with a lot of people standing around (ie, bunny slopes), or cruising through the parks, but imo the best place to smoke is on the single diamond runs if you can cut it. Experience dependent I'm sure. But just relax, chill a bit, and have a great time.
