From the Metal detecting Code of Ethics.
"I will remove and dispose of any and all trash and litter that I find."
These pictures are from a hunt a few years ago in a forest preserve. A couple of club members came upon this mess. Obviously a party spot about 50 yards into the woods where a group of people decided to break the forest preserve rules on alcoholic beverages. The club members chose to clean up the area. They hauled out 10 bags of trash.
