A few months back somebody alerted me to a couple issues of the Bradford Era that had mention of a cave, a "Neilly's Cave", in their "Round the Square" section.
This is the first time I heard of "Neilly's Cave" even though I've been searching for caves in this area for about the past 30 years. A lot of people in the area know me as "the cave guy". My outdoors group, the Allegheny Outdoor Adventures Group, does adventure hikes, including many cave visits!
I've authored guide maps to some of the regions better known caves and large rock areas. I have documented about 190 large rock and cave areas over the years. I've gotten pretty good at chasing down rumors of caves in that time.
