I don't believe there are many of the type on this forum, but people that trash our waters are clowns. It's an embarrassment how some people leave stuff on the bank or throw junk in the water. I have literally picked up truckloads of trash from our waterways over the years, but it always grows back faster than I can work on it by myself. Carry out your own trash, but try to carry out someone else's to while you're at it. The more people see this, maybe the more others will do it as well. And yes, show landowners some courtesy.
