Favorite place was the San Francisco Bay Area, but that was 30 years ago. Today it is overcrowded, overrun by government, over taxed, and excessively expensive. That's what can happen when the best climate merges with the best beauty.
Worst place was Northern New Jersey, essentially suburban New York City. Not bad in terms of things to do. Some of the same cost pitfalls as the SF Bay Area, but without the climate. Worst of all was the nature of the people -- aggressive, push and shove types. Could not trust anyone. Lying and manipulation was the order of the day.
Honestly wish I knew where one could go these days for a decent climate without exorbitant real estate and/or taxes. The best fit socially with reasonable costs seems to be hot and humid places.
Really would like a place that is free of ice and snow without excessive summer heat, and that means west of the Cascade Range along the West Coast. That area is not only exceedingly expensive, but unfortunately is now run by Antifa followers and their protagonists. I guess if you're willing to live in a tent, spread your excrement on the street, and are not bothered by violence, you don't have to worry about the taxes.
