Hey I've been to go to Ringing Rocks in Bucks County, PA a few times, but that was before I started climbing. So I didn't have my eyes out for boulders of that kind (just the ones that ring). I did climb a short wall with a friend, but it wasn't a real problem (mostly we could use the trees growing out of the face for holds). So I was wondering if anyone has ever gone there specifically for the climbing.
To the best of my knowledge, there is one large boulder (covered in paint) located just a little further down the trail from the ringing rocks. Let us know if you find any more.
