Anyone living or vacationing near Nags Head, on the North Carolina Outer Banks may want to visit the CAP museum at the Dare County Regional Airport terminal building. The same airport is where Tommy Blackburn's VF-17 Jolly Roger squadron trained during WW2. The museum also has displays and items recounting that history as well.
