Been around that area when I lived in NC, and there is a bunch of "nothing" in that part of the state, with a lowly insignificant gate, down a gravel road cut right through the scrub and pine, graded, compacted, and just keeps going.
One could hide, or make a military installation very easily out there. Even if it's a military weather installation, or they have a couple quick launch ICBM's in there.
Guaranteed NOT open to the public.
Sunny Point military terminal on the Cape Fear River, is one of the largest weapons storage facilities on the east coast. It is marked on the pilings a 1/2 mile away, on the river, and patrolled by fully armed 50 caliber gunboats 24/7. They run off everybody, even the good ol' boys in a jon boat flounder fishing.
They also have NO sense of humor, and don't discriminate, they HATE EVERYONE not authorized to be there.
