Assume you're gonna be doing some chicken necking.
Turn west at the stop light at the convenience store and head back toward the sound. Keep bearing to the left. You sould come to a small harbor on the soundside and a fish house, Avon Seafood. Run by Tilman Gray. Might be some areas around there you can crab. Most of the folks I've run into back there are pretty nice and might be able to point you in the right direction.
