Out by the river, where we used to fish when I had time for things like that, there was an old quarry, complete with buildings (all cast concrete). When we got tired of fishing, sometimes we would climb up the hill, cross the rr tracks, sneak back into the quarry, and check out the buildings. They were empty, except for a storage rack with core samples piled up on it. Also, there was one building that was obviously the smithy for the quarry. There was a brick forge built in the middle, with a brick chimney, and an open slot in the roof directly in front of the chimney – over the forge. Other than the forge itself, there was no equipment, furniture, or hardware left, except for a stump, which was obviously the anvil support.
Of course, eventually a local biker gang rented the whole place for a massive party, painted graffiti everywhere, and did about ten years worth of damage in a weekend. I think afterwards the brick forge was still there, but the stump was gone, as was anything else portable.
As far as I know the buildings are still there. The last time I was back there was when I was dating my wife, about four years ago.
It’s always been private property, so I can’t reveal the location, other than “Susquehanna River.”
