WonderWorks, Pigeon Forge, Tennessee
We did go into Gatlinburg, Tennessee, one day, but just to drive along the main road. There was too much traffic, and too many people.
Another day, we went into Pigeon Forge, Tennessee, which wasn't nearly as busy. While there, we saw several interesting places, and decided to visit one of them. This upside down looking building turned out to be a kids science museum called, 'WonderWorks'.
