My sister in law lives in Tucson and we have visited her a couple times. The Tucson area is really a beautiful desert area with great photo opportunities. It can be really hot in the summer but a typical winter day at 65 degrees is pretty nice!
Some of the photos below are from some places I'd highly recommend visiting: Tohono Chul Gardens (be sure to try the great food and drink at their cafe) and the Arizona-Sonora Desert Museum (you can spend a full day there), and the Gallery In The Sun.
