Marc Forestiere was in elementary school with me and his Mom was the den mother in Cub Scouts and she took us all there on a tour showing everything around 1970. Neat place.
As I said earlier on this thread, we used to sneak out there at night and explore as 16 year olds. I’m sure we had no business being there, but we did no harm, either. This was in the mid 50s and it appeared abandoned at the time.
