It's expensive. Right outside D.C., so the traffic is terrible. Great shopping and the metro in D.C. is good, though, so as long as you're not driving and you're making a lot of money, it's a nice place to live. As long as you don't mind cities, that is. I used to live in D.C. and I enjoy the area, but it's the worst traffic I've ever seen, barring possibly L.A. and New York.
