I was twelve-years-old spending a fair amount of time at my grandmother's cabin at Pine Grove State Furnace. Pine Grove has always been haunted, mostly due to Fuller Lake, a water-filled, old, open pit iron mine. Though the Park Service has gone so far as to send divers down to the bottom to prove that no one was killed, many people have seen ghostly horses stampeding from the old stables to the lake and into the water, making it glow a deep blue before disappearing. My story, as far as I'm aware, has never been duplicated or replicated. It involves an old iron horse that wasn't quite ready to be scrap.
