Trailrat, If you lived and fished a certain river your whole life and then all of a sudden that river showed up in all the papers, on the radio, and now every "yuppie" in the country was fishing it, you'd be a little pissed too, huh! You cant blame them...
Most of the locals care about their river because they are the same places their dad, and his dad fished, but of course there are the lame brains like you mentioned above that leave their crap everywere.
My favorite river is close to the metro area, and every weekend it gets packed with out of towners that dont have a clue as how to approach a spot without corking everyone, but i show them no disrespect...They flat out dont know any better. They wont be getting any tips or eggs cure recipes from me that us "locals" share. :p :p
