if you look at the hills in front of my house: coming here to learn and share
most of them are in Utah..only the very far left are in AZ. UT is about 1/4 mile north of me, and we are at 4800 feet elevation.
It does get warm here sometimes, but never like down in the valley, and even on our hottest days (+- 105F) the nights cool down to the 70s.
Heck, winters aren't too bad either. Although we are zone 7, most of the winter is quite mild. We only have a couple weeks, usually, that freeze hard. Those weeks may drop into the single digits though. I have seen it below zero here, but that happens rarely.
All in all, this is a pretty good place to live. The only thing that we really lack is water. If you gave us water, we could really grow things here. (and if you would stop those late spring frosts that like to kill our apricot and peach blossoms.)
