we used to have to do a boat race for people in the boy scouts. mofos would just go out and paddle around and then come back. there was the drainage runoff for water that led into the creek from an enclosed culvert. I went in there once. About thirty yards in it got pitch black, I took out a lighter and turned it on
I'm glad I did because the tunnel elbowed about a yard in front of me and I would've run right into it. When I looked to the left though there was about three homeless people in there, all red faced and bleary eyed sitting in the complete darkness. It was something like a horror movie mang.
I GTFO of there.
