JD1 is right, courtesy does go both ways. However I have found in the last couple of years common courtesy is about as prominant as seeing an albino whitetail in the woods. Its quite simple really, whether in a boat or on the bank, respect the fishing area of others. If you are having a tough day and you see someone else catching fish....don't just run over there and try and get in on the action. Likely that individual put in a little effort to find their success, you should do the same. As far as buffer zones.....don't waste your breath, boaters are showing less common courtesty each and every time out. Its not just KS either. As a generalization, nobody cares about anything other than "ME ME ME" anymore.
