I have mostly seen them between Camp Earl Wallace and Conley Bottom. I hear the creeks near Grider over to the Dam have the issue as well but I have thankfully never seen one there.
Folks can't just give up and shut up. By keeping it out in the open maybe enforcement of the current laws will start happening. No one should be blamed but the people doing it. ___ you have a cruiser but even when you were at a Marina that did not pump out you went out of your way to go get a pump out thus you are a great example of what people SHOULD be doing. There is no excuse for it and people like yourself prove that. I can't see anyone pulling this stunt in Harmon because they would be caught instantly. The stench can be quit repulsive and people would be kickin other peoples butts pretty quick.
That plus the fish and wildlife are almost always there and it would be a dumb idea even for one of these idiots that do the dumping.
But to what you said about one getting a grant and not putting the station in... If that is true that is some real BS on their end.

Buy American, the job you save just might be your own.
