I used to live there (as a child). It is a very small town, probably < 1,000 people.
I'm sorry to tell you that this is no longer the case. The townhouses are proliferating like rabbits, apparently breeding in the darkness, for every morning brings more of them. Route 7 is now a traffic nightmare at rush hour. McMansions with three- and four-car garages are popping up overnight as well. "Purcyville" is about to be part of the 50,000-house building craze the Virginia Supreme Court recently approved for western Loudoun. It's sad that the majestic sweep of the Blue Ridge will soon be covered with piles of vinyl siding.
