I just received my trail booklet for a trail I'm looking to hike. They ask that people bury their used TP so it will decompose out of sight. Of course, that goes along with no "business" within 50-100' of the trail or any watercourse, and minimum 100' of any campsite area.

My uncle once found Canadian Tire money in the woods. It was only dirty on one side. He realized what it was used for after he got back to the car and my aunt asked him where he got it.
