Well I went from 10,000 feet and 70 degree days to 118 back here in Arizona. I'm still in the "plein air" mood so I set up in the shade as the sun was going down in my backyard. I live on a cliff overlooking a river valley with mountains (called "hills" in Colorado and other places where they have real mountains) on the other side. My dogs and I hike down there everyday. There is also a horse ranch on the other side.
