My friends and I camp and fish on the Livingstone/Old Man pretty often through the summer and we usually spend the first little while cleaning up the bottle caps, cans, garbage and at one spot plastic BBs from the campsites and down by the river. We now dub one of our previous favourite spots "Dirty South" because that's what some ignorant a-holes spray painted on a tree on on the rocks along the river.
It's the catch-22 camping there is you have the freedom to camp where you please but you get people in there that think no rules and I can treat it like it doesn't matter. Guess what buddy - it does matter.
Anything we can do to keep it open and free and safe for animals, fish and people should be done.
