Great Lakes Shipwreck Museum (Paradise, Michigan)
The Great Lakes Shipwreck Museum is the only one of its kind dedicated to the perils of maritime transport on the Great Lakes. It is fittingly located at Whitefish Point, Michigan, site of the oldest active lighthouse on Lake Superior. (Thanks to Elizabeth for the suggestion.)
Henry Ford Museum (Dearborn, Michigan)
Who would have guessed that the Henry Ford Museum in Dearborn, Michigan would be the home of such incredible morbid goodies as the chair Lincoln was sitting in when he was assassinated at Ford’s Theatre, the limousine that JFK was riding in when he was assassinated in Dallas, and Thomas Edison’s last breath? Certainly not I, but it’s now on my “Must Visit” list! (Thanks to Scott for the suggestion.)
