Yeah the whole book is like that. I've peered at it.
I'm also terrible at geography.
I don't really know where anywhere is in the UK, even - let alone anywhere else.
But there is some sort of relationship... hard to pin down though?
But this thread recalled to me an article in the gruniad about the difference between what people think is true vs what is true, and the damage that can be doing. For example, the percentage of the UK that is immigrant is wildly overestimated by general opinion.
That quote from before that was "obviously" Pynchon - I would have guessed Fielding or Thackeray or someone, seems exactly the kind of musings they riff on in their novels. Was Pynchon consciously aping their style?
