Definitely second Summit, free tour and a 2 free on the smaller size beers at the end of the tour. If you stop off in Madison hit up Capitol Brewery, and The Great Dane Brewpub has a great stout.
If you go as far north as Greenbay Titletown Brewing Co, basically another brewpub in an old train station is pretty cool to stop at. There is also Leinenkugels in Chippewa Falls, WI.
