Pete Wilson, then mayor of San Diego, called it "America's finest city," which is probably debatable. Having grown up in the mid-west, and spent some time in Europe while serving the US Army, I would venture he isn't too far off the mark.
I've lived in San Diego County since 1967, some of those years in Ocean Beach, Oceanside and Carlsbad, and the last decade or so in Poway, just NE of San Diego proper. If your here in San Diego you may want to go visit the beach, or for that matter, check out one of the beach cams from where ever you are by clicking your mouse here. From that same page you can access all kinds of information regarding San Diego, too numerous to list.
