Aside from "the town is tiny," yes, probably. Just about everyone in DC's immediate vicinity are fans, and it extends throughout Maryland, because Baltimore and Maryland went without a team of their own between the time the Baltimore Colts left (in the seventies or eighties, I don't know, bastards moved to Indianapolis, of all places) and the time they got the Ravens in '96 or so.
And most of Virginia, for that matter. And maybe Delaware. And some of West Virginia, I guess. Aside from that, I'm not sure.
