OK -- really cool, and this museum fills me with information I do not need to know or retain, but I fill my remaining brain space with it anyway.
There is almost toooooo much info, and your eyes start to cross reading all the blurbs about EACH and EVERY single item they encase in the museum! Whew! Makes you want to run screaming to a casino.
If you just want to breeze through to tell people you've seen it, the one thing you must do is go to the movie theater to see what it would be like if you were to actually witness an atomic bomb blast yourself. It brought tears to my eyes, it's some scary stuff. Just imagine yourself as a little kid and your dad tells you the whole family is going to go watch the blast -- I actually know a person who witnessed them as a kid, and it's freaky to think this happened not too long ago.
