Wrong.
Washington D.C. is not a state, but its still not a part of any other state.
Maryland is closest to it though, Virginia borders it on a river, Maryland directly borders it.
Yeah, but the Maryland half is lame. NoVA has Rosslyn, Arlington, Reagan Intl., the Pentagon, Dulles intl., among other cool stuff.
well I was actually born in Silver Spring, MD. so I shouldn't talk.
