Trash in Parks!

Parks in America, like in most places I have been to are trashed up by insensitive and careless visitors. I recently visited the Ervin Park, in McKinney, TX and was apalled to see such a serene green space full of nature trashed up with beer cans, glass bottles, paper, cigarette packages, plastic covers, etc. Not many people seem to visit the park but the few who do are definitely not sensitive to keep it clean.
