I still can't believe this was free admission!! You pay 15 bucks for parking but it was more than worth it. If you love aircraft then this place is the holy grail. It has a Space Shuttle (Discovery), an SR71 Blackbird, Concorde, The Enola Gay and just about every plane you can imagine. It's all well laid out with easy access plus the walkways are at different heights allowing for some great views of the aircraft. They run iMax cinemas too showing movies about their aircraft and there is a viewing tower that allows you to see for miles around. I can't say enough good things about this place. You need to visit.
