Well, I've built jumps at Alpental too, and the ski patrolers are really easy. But if you do inverts, they might, just might rip your pass. But at crystal, if you do an invert, they'll rip your pass no matter what. And it's not fun to be chased by the ski-patrol. Some of them are REALLY good.

Skiing is life, and without life, no one would be here. So everyone owes something to skiing.
