Stash is open. Timberline park is open with small features, and then Mouse Run is still open with larger features. They were starting to get ready to build the other park over on Dreammaker with the large features but the warm really screwed that up.
Conditions are icy as fuck right now, but the parks are maintained pretty well overall.
Killy is definitely worth checking out one of those days as it's only a 30 minute drive up there from Rutland.
