Since the 1960s the nuclear powers are aiming intercontinental missiles at each other. At the Titan Missile Museum in Arizona you can have a look at one of them.
If you have enough of the Arizona heat, you can cool down in one of its caves – for example in Colossal Cave near Tucson 🙂
Arizona is the second-driest US state. The winters are mild, the summers extremely hot. Best conditions for… aircraft graveyards and open-air museums!
