I kind of grasp what you guys are getting at, but I haven't experienced any real attitude problems at Bridger--maybe just because I am a familiar face. However, I have had "locals" at Big Sky literally throw their skis on top of mine to click in in front of me, just because it was "their" mountain. Also, the crowd at the Big Sky park about 5-7 years ago was a significant factor in me quitting park skiing.
Each place has its merits, but I have found the vast majority of the new people around here are looking for a terrain park and easy-access, easy to read terrain, so they end up congregating at Big Sky. I could write a novel about each every time someone asks this question each spring (summer, fall, or winter) but I usually just send everyone up the canyon instead.
