A couple people mention the South summers being worse or as bad as northern winters.
I heartily disagree. When it's summer, you go from an air-conditioned house, ride in an air-conditioned car, and go to an air-conditioned place (store, work, etc.). You don't have any trouble driving. You don't have to scrape windshields, salt driveways, or shovel anything. You can even do outdoor activities, so long as you stay hydrated. Fishing, watersports, swimming, biking, etc. are all great summer activities.
