My brother is a New Yorker, who went to college in Chicago, stayed there for about five years, then moved to California-- LA-- and never looked back. He loves it. He does not miss winters. He lives in Northridge now, after living for sometime in LA, and actually in Hollywood (he works in the film industry, but as a techie, not an actor).
I have visited him many times, and I always enjoy it. I didn’t get to go this past winter, but I’ve spent a couple of weeks out of the last several winters, before COVID, there.
My brother drives a fully electric car, and has only native plants in his yard, and regaled me with all the grants, rebates, and refunds he has received for his environmentalism-- his house has solar panels, etc., etc. He never showed much interest in politics before he moved there-- I mean, he’s always had a liberal streak, but he really blossomed in CA. He loves being an activist there.
I’m staying in the Midwest for several reasons-- one is that the aunt and uncle who live here and were like parents to me are still living, and I like to be here for them, and DH has a good job here that he also feels good about.
But I could see some day, if my aunt and uncle were gone, and DH retired, or I were widowed, moving to CA to be near my brother. DH has siblings who happen to both be on the west coast (Seattle and Nevada-- forget the city, as she moved recently) as well, so he’d probably be amenable.
In fact, if I ever do make a major move, and don’t return to New York, CA is at the top of my list.
