After Dollywood, our next tourist spot in Pigeon Forge, Tennessee was Wonderworks. Daisy had mentioned it, but I didn't really know what it was. She just said "it's an upside down building", and even if you don't even go inside, you really have to park your car in the parking lot and just stand in awe at this upside down "mansion."
But the upside down stops after you get past the lobby. It's hard to describe the inside, but it's like a fun and science center. Kids will love this place, but it has plenty of cool things for almost all ages, though seniors might not be so impressed.
