From there site:

 Coast to coast, and right here in the Midwest, American craft beer is taking over.  We're huge fans of our local craft beer scene in Chicago, the suburbs, and great towns throughout America.  After traveling the country in search of great beers, we hatched a plan to bring them all right back here, to our home in Elgin.
