Let me just say that -- when in a pinch -- a friend of mine gets live crabs for $2/lb at BestWay, a Latin grocery near 50 and 495 (Graham? and 50). They were tiny but full. And they were female. (Grrrr!!!)
Anyone have any live crab sources to share? I know Slavin does not do live crabs anymore. I just find it hard to drag myself to the DC water front...
