We stayed at a neat little old fishing village on Wednesday night called Willis Wharf. The town, small as it was, even had on old style Western Auto which is more like a Sears or general store. We stayed at the county docks where there was maybe two dozen Carolina Skiffs among other larger boats. After reading some we found the fisherman grow clams on land then "plant" them in the estuary to be later harvested after they grow. I watched several fisherman come in loaded down with clams after only a couple hours of fishing. The clam traps were interesting too. They had big holes in the top. I guess clams are unlikely to jump, or climb out.
