Sorry to be obviously biased here, but go for Wisconsin, man! We have a ton of relatively small breweries throughout the state that are pretty good. Oh, and Miller, if you're into that, is in Milwaukee. I'll admit I'm not so much into Miller, but Leinenkugel's (now owned by Miller but still run the same way as before) is brewed about 20 miles away from my school. There's also places like New Glarus and Point breweries that are pretty well-known in the state, along with a few random bottles I have come across. Nice scenery, too, especially in the Spring/Summer.
