I was grousing about not getting Lagunitas in Indiana and happened upon this website for folks in the Upper Midwest - specifically IN:

At random I chose Three Floyds (close to Chicago in Muenster IN):

I specifically looked for their 'Dreadnaught' Imperial IPA and absolutely loved it. I am not a big beer hound but every once in awhile I get into a beer phase. I might start looking around for more midwest brewed beers. I know Bells Brewery up in Kalamazoo, MI puts out some great brews - 'Two-hearted Ale' comes to mind immediately.
