Pretty cool. I can't count how many hours and days I spent back there, between ages 8-18 or so. The lake wasn't a lake, as long as I've known it. As far back as I can remember the dam was broken at the south east corner.
I know I previously mentioned on here that I had a close call with the law while exploring the menantico colony buildings. Not long afterwards, Weird NJ magazine did an article about the same, and it probably generated quite a bit of trespassing in the area. I got out without being charged- but it's doubtful I would have been so lucky after the article was published.
