I spent my summers growin up in Nags Head. It is a gorgeous area, I still surf and fish there all the time. I have never gotten to hunt around there but have been fishing down there in the winter and was more amused by all the ducks than the 50 stripers we caught. It is getting too commercial however which is very unfortuinate. I had trouble getting around for all the people down there this summer.
You said that you are only going shooting so you should be fine but as an aside, and I am not sure if it is the OB Gun Club or not, but I know that there is a major, fairly repitable outfiter in Currituck county that has been under a major federal investigation for baiting. I am not trying to hang the innocent here, it might not be them, I do not even know if they do guided hunts or not. I have no idea how many duck outfitters there are down there. This is from a solid source (my father and god father work for game and fish in VA, Dad in Fish, god father in game). Don't be that guy who is hunting over bait when the man pulls up. Even if you are on a guided hunt they will most likely hang you with the rest of em.
