It's a great park with some surprisingly enjoyable rides. Lightning Rod is one of the most intense coasters I've been on. Definitely a little rough at times, but man it does not hold back at all. And it's kind of hidden in the layout of the park, with a lot of the track over the top of a hill.
A visit to the Pigeon Forge/Gatlinburg area and the Smoky Mountains is great trip, especially with kids. Lots of quirky nonsense to enjoy, as well as some beautiful nature.
