San Diego.
I've lived in most of the western states at one time or another. My father had some serious wanderlust. Usually stayed away from towns and had property in wide open spaces miles from anyone. But went out to San Diego for a summer a long while back and fell in love with it.
Took a long time to get use to so many people and the outrageous beach tax. But there is something about this place and the people. Just works for me. Miss the Rockies, but the beach makes up for it.
After I retire, I am considering moving back out to northern New Mexico. It is truly the land of enchantment. Then again, I may be too citified' for that now, and New Mexico may have changed too much.
