I stayed at NBK shelter one night in March 8, 2015. I was too tired to let the somewhat creepy feeling bother me except there was mention of a persistent bear in the logbook and no food hang cables and it was after dark when I arrived so finding a suitable tree and limb to use for the food hang was difficult but I eventually found one. Also no privy but I'm used to poopin in the woods since I used to spend lottsa time in wilderness areas where privies are non-existent. No sign of the bear or "spooks, goblins, monsters or any other supernatural phenomenon.
