Someone on HN previously posted "Which of the 11 American nations do you live in?" And while I don't agree with all of these -- Dallas and Austin are certainly not "Greater Appalachia" and probably deserve some kind of Texas "nation" of their own like "Tidewater" -- it's certainly true that "American Society" has many distinct parts. (Moving from Colorado to Connecticut to Mississippi felt like living abroad in three separate countries.)
