Wisconsin Auto Museum in Hartford, Wisconsin...
Interesting history of Hartford is where Kissel Cars were made...Later Hartford was the place Chrysler made outboard motors.

I would plan on the full day. They open around noon and close at 4:30PM. It's not enough time for me. My stupid friend dicked around and we lost an hour to start. I never made it to the third floor. A wall of Flathead Ford intakes, Weslake 318 Plymouth engines, Miller/Offy engines, custom cars, etc.
