As far as park goes, imo, it's not worth that kind of drive especially if it's shitty weather. I went a week ago(2 hour drive). Skiing the mountain was awesome just wasn't feeling the park setup. I mean, it's typical late April skiing in mush, so you're not gonna get a baller park.
They have 1 kind of decent 20'step-up jump that has probably melted down quite a bit, some decent down rails, dfd was closed off, and a decent flat bar.
This is what they had a week ago, but i'm sure they've pulled some stuff out or made some changes. I don't really like their lips on their features.
I guess it all comes to How bad you want to go skiing? Like i said skiing the mountain is awesome typical spring skiing. I'm gonna go Friday and probably session some stuff. i really liked the long snow making pipe up top
