The National Atomic Museum was awesome. I've always been fascinated with nuclear stuff - especially the history - and regularly check out Los Alamos when I'm near Santa Fe. We were in Albuquerque for the New Mexico Marathon this weekend and stayed around the corner from the museum (in fact the marathon made its final turn at the corner of the Atomic and Art museum.) The exhibit was great - well organized, tons of unique history, and good video / audio / pictures. It's easily worth an hour for anyone interested in nuclear history. And - as a special bonus - the museum store is great.
