This reply is several months late, but for hills in the UP you have 3 general areas - Marquette Mountain just outside of Marquette, the hills way out on the west end by Bessemer/Ironwood (Powderhorn, Indianhead, I think they are joint owned) and those further up the Keweenaw (Porcupine Mountain, Mount Bohemia, and Mont Ripley.) If you want the steepest drops, Bohemia is the place to go. I don't snowboard, I ski, so I don't really pay attention to who has the most half-pipes, etc. If you want any semblance of nightlife (whatever you can get in the UP, remember that the IGA closes at 9), Marquette is the place. Often for Marquette Mountain there are 2-for-1 lift ticket coupons in the phone book or the newspaper.
