I go to school at Michigan Tech in Houghton (about 40 minutes south of Bohemia) and it is pretty epic up here right now. I was at Bohemia yesterday and they had a foot of pow pow. The only downside is that a lot of stuff will get tracked up pretty quickly, but it snows literally every day up here (only 1 day without snowfall since Nov. 30), so it's only a problem when it's busy (read: Saturdays).
Anyway, I'd recommend coming up during the week or for a long weekend. You really can't pick a bad date, at least until the lake freezes over.
