Let's not forget....There's the Vibrator Museum in San Francisco. yes, I AM talking about what you think I'm talking about. The Vibrator Museum displays some of the first instruments of pleasure, which were actually originally used by physicians to cure women of stress-related disorders. The museum is set up in the store, Good Vibrations, in the Mission District. You won't find the Carnegie Foundation on the list of contributors to THIS museum!

There is the Mustard Museum in Mount Horeb Wisconsin...don't know about any ketchup museums;-)

There's a museum in Doylestown, PA that is the biggest collection of Americana you could imagine. Like going through someone's gigantic attic. Does anyone know its name? Then there's Harold Warp's Frontier Village in Minden, Nebraska, that just goes on and on -- pioneer stuff spread out over several acres.

Tesla museum in Colorado. If you know much about physics, radios, etc. it is a great draw for the historical information, but it was tucked away in an office/industrial building, open only a few hours a day, almost devotees operating it, and some strange merchandise for sale.
