I cant say for sure cuz I havent been there but go anyway, I heard its insane there (no boarders either if you like that). Im goin with my school, I mean if its less crowded than Vail (which it has to be) than its all good. March is prime season, as you probably know, and I heard Alta rules, so go for it. For me, Alta/Snowbird are on my highly anticipated to ski list, up there with mammoth, chamonaix and other crazy Euro mtns, so Im there.
