I got all of those benefits from my group of friends when I came out to U of U. I guess if you go to a place like boulder where only 5% of the student body are legit skiers then a team would help you find them though. And the USC thing sounds pretty pimp with that house they can stay at and shit.
I don't even think Utah has a freestyle team, but I can tell you if it's a school you're considering it doesn't matter much because in the dorms you shouldn't have much of a problem finding a crew to do all those things with. No place to stay, but that doesn't matter much when your dorm room is 30-45 minutes from all the mountains.
