Have had a pass at bohemia every year it's been open. It kicks ass! It is the only mountain like hill in the Midwest. If you go, bring your rock boards. They don't make any snow or groom anything, so rocks poke thru everywhere (especially when they have under 100' of snow), I've killed three sets of boards up there. But if you want an awsome hill with glades, cliffs, and powder this is the place.
Ripley is fun to mess around for a few hours.
Marquette is cool, in my opinion it has one of the best parks in the midwest. But that's starting to become common knowledge.
