The Henry Ford Museum in Dearborn, outside of Detroit, has the actual Rosa Parks bus in their collection. You have the opportunity to climb aboard and sit in the same seat. It’s a great educational opportunity. It’s just one of many historically significant items on display. I really recommend a visit to it if you’re in the area as well as Greenfield Village, a living outdoor museum, another part of the complex.
