I'll be driving through the area but will probably pass on that one, as good as it sounds. I've already visited a WWII sub in Muskegon, Michigan (which was definitely cool) and hit several Great Lakes museums, the best of which was the National Museum of the Great Lakes in Toledo - outstanding. The Great Lakes Shipwreck Museum in Whitefish Point, Mich. (near where the Edmund Fitzgerald went down) is pretty good too. Might have to transit Gary later today on my way to Chicago but we'll see. Anything in Milwaukee or its environs I shouldn't miss?
