BBQ and Oysters! Accokeek MD (DC area)
I just come across a GREAT RF place about 20 mi from Washington DC:
B&J's Carry Out:
"Famous for Dixie Style BBQ" on Rt. 213 http://www.yelp.com/biz/b-and-j-carry-out-accokeek
Great Q, spicy/peppery, and fabulous local oysters (usual sandwich with tarter sauce and letter) Toasted buns, OMG. I even got one of their T-SHirts.
