This issue is definitely fresh in my mind right now. We are having the first really nice week of the year, and all of the nimrods are out cluttering up the public access with beer cans and empty worm containers (not to mention other unpleasant things).
I don't know whether to laugh at them or cry.
On one hand it is comical to see 20 guys fish the same pool of a small river (I even saw two of them in a boat five feet off shore), but on the other hand, I know what its going to look like in two weeks.
Thankfully, like you guys, I don't usually fish the public access parking lots. I usually venture further into the woods. I will pick up trash, but I do draw the line at used condoms though.
