Maybe my expectations were too high, but I really wasn't particularly impressed. I just didn't feel like there was very much here that I couldn't learn from a 20 page booklet. Lots and lots of things to read, not nearly enough firsthand experience type of exhibits. There were a few things about troops in the bunkers during a test, but it was only a 1-minute story that probably could have shared more interesting details than they did.
It also felt quite a bit like propaganda. Based on the exhibits there, nuclear everything seems like an obvious choice with no potential for risk. Drop nuclear bombs - you win the war. Fallout??? Not really brought up. Chernobyl? Mentioned, but only very briefly.
The $12 seemed a bit much for how little was actually here, but considering that the time we spent here probably saved us $100 at the tables, it's a bargain??
