depends where you going to be on the Wisconsin UP line. on the west side there is Indian head mtn, Big Powderhorn. in the middle there is Ski Brule, East side there is. Pine Mountain and Norway mountain.
Bohemia. Best skiing you can get in the Midwest. Also, if you're heading up there this weekend, Saturday is their Mardi Gras celebration, which means it will probably be crowded (so three person lift lines max ) and there will actually be girls. The snow should be halfway decent too, since we're getting around 6 inches tonight and hopefully a few more tomorrow.
If you're looking for a good park, go to Marquette.
