I mentioned this once before, but the endless seeming suburban sprawly area between Southampton and Portsmouth probably is the most America-like part of the entire United Kingdom.
Nowhere in America would you have a town named Hamble-le-Rice.
Preppy rich people with yachts? I think there's a bit of that
Mount Desert Island, for one. (Marguerite Yourcenar lived there, by the way.)
For a bunch supposedlyunconcerned about material things, bohemian types always manage to live in the nicest places. You'll never read "Oh yeah, East St. Louis - Marquerite Yourcenar lived there."
