This is a very cool place off the beaten path. I love that the exhibits are informative and interactive. The exhibits walk a fine line between not glorifying the Cold War or discounting the efforts of the people who worked at the Test Site. It's hard to believe all this happened about 60 miles from my door step. The Ground Zero theater is not to be missed. I thought the exhibits regarding Las Vegas back in the day were great. They even have a piece of the Berlin Wall and a piece from the Ground Zero from 09/11. My husband and I spent a good two hours at the museum on a hot Sunday afternoon and had a great time. The gift shop is fun and a bit funky(Does anyone really NEED an Albert Einstein rag doll?). I picked up my fabulous Miss Atom Bomb 1957 refrigerator magnet. Don't think it's for really young kids, but did see a lot of families there.
