There are tons of good beers in the area. Surly is what you want to make sure to hit early. If you have to stay in Bloomington, that is okay, they will sell it there. Drink Furious, Bender, really anything they make is great. I lived in the twin cities for two years and miss a lot of beers from that area but none more than Surly.
I actually have a Furious clone in primary right now. The color isn't right but I hope it still gets close!
