If you find yourself a little bit south in Tucson, I found the Pima Air & Space Museum to be very good.

There's also a Titan Missile Base turned into a museum

Also if you have time to head south to the Tucson area Kartchner Caverns is awesome. Very interesting history of how this whole huge unknown cave formation was found

Tombstone is worth a day especially if you like the movie/history

Bisbee has a really cool mine silver or copper or something
