Let's talk about Americans for a moment, in fact let's talk about talking to Americans. Now there are a lot of Americans travelling around the world and quite a few of them have a grasp of World Geography that leaves mine standing. (Actually quite a few kids in villages in the middle of the Amazon jungle have a knowledge of World Geography that leaves mine standing.) However most American tourists have a bit of a blind spot when it comes to this sceptered isle. My American geography is a bit sloppy but I could probably locate Pitsburgh on a map more easily than they could locate, for example, Sheffield. The two exceptions to this general rule are London and Stratford. No self-respecting tourist coming to England would miss out Stratford any more than I could go to New York and not go to the Empire State Building or visit Washington without seeing the White House.
