I grew up in Pittsburgh, and there are good bits around CMU. There are definitely some bookish people there. It's not as bad as a completely random town in the middle of the country.

The weather's pretty bad though. I was surprised to read a few years ago that Pgh was one of the least sunny towns in the country. Then I realized why as a kid I associated sun with being on vacation: when we were on vacation, we were in other places, and everywhere else was sunny by comparison.
