Welcome David,
As an ex-patriot of NorVa all I can say is if you don't know what's interesting to shoot there (and you live there) define your interests first. Its a big area. There are a number of NorVa members wondering why you aren't down at Great Falls, or in the District at the monuments and museums, Front Royal and Skyline drive only an hour away. Or just go ride the Metro into the Washington Navy Yard in SE and wave your cam around yelling $50 to the first guy who can take it away from you. That should generate some interesting shots if you can shoot while running backwards...fast.
Please post those shots if you do.
Ok, got some good ideas yet? But seriously, welcome to the forum and hope to see some posted shots from you soon.
