Not as far as Hatteras, but there's nothing of any terror value there except a lighthouse. All the tourists have gone home and there're just a bunch of surf-casters and locals residing in the area now. Inclined to talk more about potential targets, one of which I'm near, but loose lips sink ships, even though the sons of monkeys have already visited once, in the Summer of 2001, before they knocked the planes out of the sky.
I did a lot of research on Kitty Hawk this summer on one of the previous threads when the name kept popping up on jihadi posting boards. (At that time, we speculated it was probably in reference to the aircraft carrier, not the NC coastal town.)
Two things struck me about Kitty Hawk (which I have visited): its symbolism as the birthplace of flight, and it's relatively close proximity to Virginia Beach/Hampton Roads/Norfolk. Talk about an area rife with HVTs...
Also: lets not forget the scuba divers from earlier on. The relative desolation of that area during the tourist off-season could present an opportunity.
