The National Atomic Testing Museum in Paradise, Nevada, documents the history of nuclear testing at the Nevada Test Site in the desert north of Las Vegas. The museum operates as an affiliate of the Smithsonian Institution. Although I thought that my husband would enjoy this far more than myself, I was wrong! The museum is well laid out with many artifacts, the staff very knowledgeable....we were there for ages. Amazing to see how the world has changed over the decades. Highly recommend this while you are in Vegas.
