Actually... The Detroit airport is out by Dearborn, and Dearborn is home to the Henry ford museum and Greenfield Village. Basically, Henry ford's Disneyland which is a must see. Lots and lots of similarities with Early disney designs (Walt and Ward Kimball visited Greenfield Village prior to 55) including an operating steam train, model t cars you can ride in, horse drawn omnibus, "Main Street" working farms, and the Thomas Edison Menlo Park. The indoor museum is also a must see with the Rosa Parks bus, presidential Limos, etc.
Dearborn is one of my favorite places to visit right up by Disneyworld and Land.
