there is probably a greater cultural distance between e.g. the Pacific Northwest and deep South in the US than there is between many European countries. This is a little overstated. Geography aside, there's a lot of similarity in the look, feel and culture of suburban USA no matter what part of the country it is. The big differences in the cultures in the USA are between the three or four largest cities and the rest of the country. There's also a handful of outlier areas like New Orleans or Honolulu that aren't really like anywhere else on the planet.
