they've got several pieces of heavy equipment back there going. And lots of security. As i was walking back there was an older couple headed there too. Well as they were walking back past the ticket booth, a security guy in a car stopped them and talked to them for a while. I was still at the pavillion, and kinda hid until the guy left. I was scared of getting talked to. He drove on the dirt path between trails end and the pavillion and on into a gated area and i made my escape.
But i did snap a picture of them tearing down the building with the bathrooms, they had part of the original fence open, but i couldn't see past it.
on the boat ride, there were a couple pieces on the far shore of the lake, so it was hidden by the trees until you were past it. They also have a fence up around pool area, dividing it from the lake. There's still everything it the lake, as far as i can tell. I haven't found any one to talk to yet though.
