But "what you saw" isn't necessarily representative of the state of things, either. Arlington, VA is (was?) one of the nicer places in VA; generally expensive, etc. When I drove through there, the van in front of me at a light was car-jacked, and the person in it chased down. I'm uncomfortable driving through Arlington because of that; even though it's not representative of the area. Admittedly, this was years ago... but the point stands. My experience is not representative of the actual facts.
