I didn't see any of that, so it's good you reported it.
I was there twice this week and saw a plastic bag at one location which could have been from someone that dropped their poop bag and I saw a pair of shoes in the grassy area behind one of the big trees. I went up pass the springs bridge and about a quarter mile past that on the Southside. I could tell there had been people up there just because they had created some cool heart's made out of pinecones and some other things but other than that it looks beautiful.
