Interesting thread! I'm sorry to hear that the water level is dropping so much in the PB. The great Pine Barrens aquifer is one of the things that John McPhee talked about in his famous book, and how the water down there was all good to drink.
And for Halloween: Long ago, two days after Halloween, I was hiking alone under the Palisades cliffs along the Hudson River (no, not a Pine Barrens story), and it was dusk, getting dark, when I came to a long unused and overgrown one-time boat landing dock and picnic area called Twombley's Landing, and it was there that I met two real witches. True story. Very scary!
As for the NJPB, I used to want to get someone to camp out with me down there on Halloween night, but I never could.
