Absoluetly TUCSON !!!!!!!! per the former posts. Then if you have a little more time , drive north to Phoenix to Mesa and visit the Fighter Museum in Mesa . at FALCON Field. Largest museum of fighters in the world. !! All Nations. This museum is going to be moved to Seattle , Washington soon so do it now.!! On your way North on Interstate 25 as you near Phoenix and look to your right you may see tails of large aircraft. Go there. Its called Chandler Memorial. Ok to drive thru but look and dont stop. It is not a tourist attraction. You are not in danger but they dont like people stealing stuff. You will see the largest group of 4 engine piston aircraft in the world. DC-4, DC-6, DC-7 and other stuff. Dont be surprised if you drive down a runway to get to the aircraft . Its Ok. Not a lot of activity. God I wish I could be you guide.!!!!!
