if all -- ALL -- you want to do is ski bohemia when you're up here copper harbor's a nice place. it's sort of a ghost town this time of year. beautiful place in the summer, though.
i'd suggest staying in calumet, save yourself about 10-15 mins to bohemia...the americ-inn is nice, albeit a little bit pricey.
ripley's a pretty fun hill. steep enough in places to really be fun, lots of kickers. they have snowmaking so plenty of cover. relatively cheap, too.
