Bridger is good buts its overrated.
Its really small, and crowded on the weekends, that being said it is cheap.
park is not good, also you get about two months less of skiing.
Big sky is an expensive season pass.
the park this year at big sky has been underbuit, but the features are overall nice.
The only long line is the tram, and that is about 10 minutes.
Well worth your money IMO
