Big Sky and Moonlight are about an hour away from MSU. Bridger is only like 15 minutes away which is reeeeal nice but they dont have a great park. Good mountain overall tho. If you can, Live in Roskie, and if not, South Hedges. Avoid Wangford at all costs.
Also, at least when I was there (2 years ago) the girls were ugly. Like a 7 in my hometown would be a 10 up there.
Its also a small ass town, so if you're trying to do stuff other than ski and party I'd recommend somewhere else
