Its this big pit in Sussex county that is 13 feet deep and during the fall it fills with water and usually drys up in the summer, and in the fall people go thier and throw in rocks, cans, bikes, fence posts and what ever else they can. And in the summer when it dries the bottom is just mud no trash or anything. They think when it's full there is this quick sand like stuff at the bottom. When I went I threw a Log, Brick, soda can, and a Godsmack CD in to it.
