The facts I've got so far are that it's near The Pitt, but it's the kind of area that may not have been as devastated by a bomb, or had as many problems with a lack of (and also the following battle for) technology following the war.
What I'd like to know is if there were any vaults near there and they survived the initial bombings, and if their lifestyle either kept them alive or caused them them die out. It would be interesting how that sort of culture would evolve in Fallout as well.
