Greetings, cdjack, from Twin Falls County in southern Idaho -- the state everyone's heard about but no one can find on the map!. Dawn and I moved here in 2018 after living in Arizona for 40 (me) and 28 (her) years. Like you, we didn't like the 218° degree summers, as well as the ever-encroaching drought and population growth. The rural southern part of Idaho has four seasons, excellent soil, a huge and productive aquifer, a very small (in comparison to its land area) population, and --if such things are of interest to you -- it is one of the politically reddest states in the country.
We found that, although we moved here with the intent to homestead (which we did), that there aren't many homesteading networks here; not that there aren't a lot of homesteaders, but homesteaders, tending to be more individualistic people, might not want to advertise their capabilities and interests whether to invite attention from Californian wannabee transplants or the gubbmint. Of course, you could check out homestead magazines like Mother Earth or even the local Craigslist to get some good inputs.
Either way, welcome to the forum and good luck with your searches; if you have any other questions, post away; there's a lot of folks ready and willing to help!
