I hike frequently in JD Park, it was a WWII radar training base. To my knowledge there is only one WWII era building there today, I think one of the rangers lives in there. There are a variety of terrains in there, everything from sand dunes to pine forest. You could get lost pretty easily in there today but who knows back in the 50's? I've seen some game suitable for shotgun hunting in there, including wild turkeys multiple times.
