Rivnuts from Homestead, PA on 5/4/2020 6:52:36 PM:
For info, the very short side trail (maybe 200 yards long) has been upgraded with crushed gravel into/through Dead Man's Hollow about 20 miles outside Pittsburgh just before Boston, PA. There's not really much to see albeit there is a couple of remaining concrete walls of former buildings now covered by graffiti.
There were no ghosts to be found at the time I passed through today. :-)
