I love Tucson and have been here Since 2005. Cooler than Phoenix due to a higher altitude. Surrounded by 4mtn ranges. Beautiful. Love the summers as no snow birds. A big small town with excellent medical care. Cheap. When I was in SE Virginia I lived in air conditioning in the summer. Here too but dry heat really is more comfortable. My body has acclimated and now I am colder than I used to be. You adjust. Early morning and evenings are comfortable. Friendly people. Good food. Lots of restaurants. I’d never leave here.
Family has lived there since the 60’s. I have a second home there. Know all about it. All you say is true ...weather wise. My problem is the politics.
