I have not heard of any oil appearing off NC, at least from the Gulf oil spill. It has not even made it down around the bottom of Florida or even came up to my part of upper Florida. If it had, it definately would be big news for us here living on the beach.
Market, I live in St. Pete and they don't expect the oil to reach shore here. The Gulf Stream should actually keep it offshore. We are worried about the fishing offshore though.
