There ya go...pick it up. I too see folks trash out local fishing holes and ramp areas, but I've never been able to put a particular race with the problem...in fact here close to home where I launch my jon boat off a county road, it's about all white folk.
My neighbor has used the launch area for as long as I can remember....he's in his 80's and I'm just a pup in my 50's...it never bothered him to wade through trash to get to his boat, but it does me, so I clean the area up every spring which usually nets me a 55 gallon barrel full of beer cans, wine bottles, pop bottles and bait containers.
It's not just the hillbillies either.......I know a rather nice fella, a cop from a nearby town, and I found him and his dad fishing one afternoon a few springs ago, one of those days when it's almost completely calm, with a string of crap...bottles, wrappers, etc were strung out from the side of their boat to about 75 yards down wind...looked like crap, and he would probably have ticketed somebody for littering if they were tossing that out of their automobile windows.
I figured they were surprised that anyone else was around to see them.
