never saw anything like that, but if they behaved like jerks, they deserved to get kicked out.
I am definitively for skiing, but i concede that on powder boarding is a also lot fun.
I seen it happen 2 times for being jerks. It was a really crowded season there and the ski portal were not playing game.
On that trip I saw them kick quite a few people off the mountain a lot of them being snowboarders doing REALLY and I mean REALLY stupid stuff. A lot of them on one trail that was one of the main ways down the mountain. THere is a sign that states no jumping and snow boarders were making the jump right off of it. It was a good 6-7 ft down on the side of it so it was pretty dangerous to other skiers/boarders on the mountian. The threw a lot of people off right there.
