I called Plumstead Township and a friendly woman said she would ask around the Municipality about Jumping Brook, and call me back...which she did. But so far, no one in town has any idea about the place, which I find amusing. But she said their zoning officer would be in on Tuesday and that she texted him about it, and she would call me back then. Seems like you opened a can of worms, Bob. She asked why was I interested and I mentioned about fishing, and how others may be interested in birding, and or botany, and hiking. She now is curious herself so maybe the township will discover their own little hidden spot. Gee, if I knew the place was such a secret, and, I was a hitman for the mob...
