I recently went through Auburn, Indiana and stopped by the Cord/Duesenburg/Auburn museum. The place was amazing, and there were two other classic car museums nearby. Also, a railroad museum, an air museum, and the worlds largest military vehicle collection, all just a few miles of each other.
We only had an hour for the one, but it's definitely a place to visit for a very complete day. Other good ones are the Henry Ford outside Detroit and the Imperial Palace collection in Vegas which is quickly being sold off.
