When I was a kid we went on a road trip through the mountains in PA. All along the roads are road signs stating watch for falling rock. My dad told me and my siblings that the signs were there because along time ago when Native Americans lived there that there was on named Falling Rock. He was kicked out of the tribe for murdering the chief. After they kick him out they found out he didn't do it and went looking for him only to never find him. That is why the sign are there cause till this day he has not been found. Of course we believed him lol.
