VA crabbing season opened today (3/19), MD opens 4/1. It's still pretty chilly for them to be plentiful so much of what you'll get locally will be brought up from the Gulf and the Carolinas. The Dancing Crab on Wisconsin Ave. and the Quarter Deck in Arlington are easy to get to but call ahead to make sure that they have crabs.
As we get closer to Memorial Day, the local crabs will be more plentiful, but even then, local restaurants often use the "imports" from further South.
Maybe some of your friends with cars will be up for a trip to one of the really good crab houses near Baltimore, in Southern Maryland or on the Eastern Shore. It's worth the trip for the local color and the much better prices. Here's one crab lover's list of some nearby favorites. By no means exhaustive, but a good starting place. http://www.bluecrab.info/forum/index....
