Tucson
There is old Tomestone if you are interested. Many of the old westerns were shot there. Marana while interesting is next to impossible to get onto. There are several aecurity conscience operators on the airport and the gate is at least a mile from the airport. You can not see much from the road. The Pima Air Mu. is always a treat. Visitor friendly and lots of one of a kind aircraft. DM use to do tours two Saturdays a month, but that may have be stopped for now.
A couple hours up the road is Phoenix. At the Mesa airport, the CAF keep the AZ Sq aircraft a HE111 and B25. Plus a few others. And the Chaplain Fighter Mu. Go there quickly, as it is moving to Seattle in the near future.
Enjoy your trip.
