There are a few things I'm not fond of: tornadoes, wildfires, periods of extended drought, heavy traffic, extremely high crime, dislike for Californians (Oregon & Montana). A few things I don't mind: cold and snowy Winters (it's just mountaineering with more infrastructure and support), regular storm seasons, earthquakes and hurricanes. A few things I really appreciate: mountains within a couple hours' drive, lots of outdoor activities, younger and more active and better-educated populations. Maybe Utah? (But: http://www.latimes.com/nation/la-na-utah-drought-20150530-st...)
Unfortunately, snowfall over the entire Rockies seems to be on a declining trend (http://usatoday30.usatoday.com/weather/news/2011-06-10-clima...), so any place that relies on the Rocky Mountain watershed is going to be dealing with drier conditions for the foreseeable future.
I'm open to suggestions.
