Look at Inland Southern California. Great weather, tho some heat in the summer. Where I live (Hemet, CA) as long as you get out and ride early you are fine. Homes are quite affordable now. Many people are snowbirds here and in the surrounding area. Maybe you could find a winter place here, and keep you place in Maine for the beautiful summers. And it doesn't have to be H-town, there are lots of nice snowbird communities in Riverside County or the San Diego area. My husband and I also kind of like Yuma AZ in the winter. Yuma would be way too hot for me in the summer.
