2.
A neighborhood and metro stop in Arlington, VA. Very urbanized and filled with office buildings, apartments, condos and, of course, dry cleaners. More sterile than the other areas of Arlington (which is saying something). Typical resident is the Arlington Girl. Rents are extremely expensive, for reasons unknown to all.

Home of Rock Bottom Brewery. Wednesday is fire code violation night!
I'm so jealous, Sarah just got a studio in Ballston for $1300 per month!
