I fish the last saturaday. It was heavy snow, sometimes rain. It was cold. I was fishing above a fellow. He was an old gentleman and I finished fishing the water above him before he did his. In the mean time, I actually stopped fishing and trying to warm up my hands. But I still finished before he did. I walked up to him and asked if I can fish a distance below him. Had a nice chat and off I went. He was happy fishing his area and so was I.
Instead of applying more rules, why not focus our energy to better educate others WHILE we are on the float.
You asked nicely if you can fish below some guy, and hopefully next time, he will do the same cause you are setting an example to him. Show an example for picking up trash, lose lines, leads, the art of C&R, etc...
So what people stand in one place... I do both. Some day more walking than fishing, other day, more fishing than walking... You can't tell me to hurry up and fan cast. I like to enjoy my time out in the river rather I catch or not. I don't want 50 people behind me staring at me with angry eyes hoping I should hurry up and finish my cast... Come on now... The enjoyment of fishing is not just fishing, it is who you are fishing with, the natural, the time in the water, the sound of the eagles, and the ice cold water...
I also see how rotating fishing method can benefit as well. If you choose to practice that and see a guy standing there, ask and go around him.
