dude, i was just at bridger this weekend. they have a really small park. 1 actual table, about 7 foot, some boxes and rails, and a roller.
if you're coming to montana, of all places, you're not coming here to ski park. you're coming here to scare the crap out of yourself on steep gnarly shit. or rip it if you're good enough.
but listen to these rules if you're going to bridger.
1. bring a beacon if you plan on going anywhere besides main runs.
2. bring a buddy, or meet some locals
3.don't go anywhere out of bounds or on the ridge without a local, or a good buddy.
a lot of the stuff at bridger cliffs out, and if you don't know where you're going you will be in a world of hurt, or stuck hiking back up.
if you follow those things you'll have a blast skiing one of the best big/ small resorts in the country. big sky has a lil more to offer in terms of size, but it's more expensive, and more populated. if you want to shred park though, big sky is pretty legit, but not the best park you'll ever ride.
try hollerado or utah for that.
