We are at 5,000 ft. so it does cool down at night. We'd run a box fan at night, with the therm set pretty high.
I love the high desert and the rocks. But it is not really suited to humankind....I've been to ancient Anasazi sites and really wondered how they were able to farm....told by experts that climate has changed since their days. Used to be more rain 1,000 years ago....
