That page lists ten hobby shops in the entire state of North Carolina. None of them is within about 150 miles of Nag's Head. And the one in Wilson (which I happen to like) isn't listed.
Model Railroader does list the one in Wilson (it's called The Antique Barn), and one in Cary - at least 200 miles from Nag's Head (probably farther).
The situation in reality isn't quite that bad, but it's pretty bad. There used to be a decent chain of hobby shops called Hungate's, but it seems to have closed all its stores in eastern NC - if not the whole state.
North Carolina modelers, like most others, learn to make do with web suppliers, and occasional trips to places like Hobby Lobby and Hobbytown (which at least has a decent kit selection - but the nearest one is about 2 1/2 hours away from me).
If you're going to Nag's Head within the next few days, you might want to take the drive up to Hampton, Virginia. The IPMS Nationals are being held in the Hampton Coliseum, now through Saturday.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
