Re: Retirement where?
Central Coast of California. Cooler than the L.A. area and warmer than the S.F. area. Year-round riding. Mild temperatures. Great riding roads. Humidity usually between 40 and 50. Lots of retired military in my town (Lompoc, CA) who have been posted around the world and come here for the climate.
Of course, as others have pointed out, you would have to put up with one of the most dysfunctional state governments in the country.
