I agree that the problem seems to be more urban. I've notice in my travels in the western parts of the U.S. - Idaho, Colorado, Utah, Montana - and Europe you just do not see what I call the "disposal society" mindset. Perhaps the individuals that live in these areas more appreciate and respect their natural surroundings and history. When I was growing up, I had access to a relative's lake in western KY and ultimatley was denied access because of the trash other people were leaving behind.
