tons of parties, but for the most part they are like 5-1 dude to chick ratio. There ARE chicks here idk why people say that there arent.
As for skiing. Bridger bowl is the smaller local area. Most of the locals swear by it but a lot of the gnarliest, best terrain is on the ridge, so you need a beacon and knowledge to ride it.
Big sky and moonlight are farther away, but I personally think the better option. The terrain isnt as technical, but they have some good open steeps and what not. Moonlight has easy access to the chutes.
As far as park, neither resort is near to level of any summit resorts, or someplace like park city. Bridger has basically no park. Big sky has a pipe and usually 2 or 3 somewhat big jumps (i think they were like 55 feet last year? mebbe a little smaller.) moonlight lacks in the jumps, but always has sick rails and jibs set up.
as for the film program, no clue on that.
