I LOVE San Diego. Different strokes. I would never want to live in the U.S. Southeast. I already have a few affordable senior apartments near public transportation and less than five miles from the Pacific scoped out.
But if money were not much of an object, then a little house in Maui. Or near Kona. (Healthcare is better in Hawaii than here.)
Anywhere in the world, if I could be employed and a citizen for awhile before retiring? France. Either Lyon, or somewhere in Alsace. I speak the language fluently and know the culture very well. And healthcare is ideal. I also know a lot -- well over 250 -- of people in France (former students of mine).
