I know this is an old topic but on the subject of people crowding you. I was fishing in zone 2 when 5 little kids came up on bicycles and started fishing with power eggs. They were on both sides of me casting in front of me. I just moved to the closest kid and literally got right behind him and started casting everywhere he casted. When he figured I was crazy and moved I went to the next kid. After a couple minutes I had the hole to myself again.
A buddy of mine walked up on a guy sitting on the bank hidden up in some brush in the C&R area using night crawlers and had 2 fish on a stringer. He said,"Sir, do you know that this is a catch and release area and you are not allowed to keep any fish here?" The guy said, "No, I didn't know that." Then my buddy said, "Did you know that this area is flies only and you are not allowed to use night crawlers here?" The guy said no. My buddy said, "If you turn those fish loose and they swim off with no problem and you dump those worms out into the river I won't write you a ticket." The guy gently let the fish go and dumped the worms out and graciously thanked my friend for letting him go. Only thing was my friend isn't a game warden.
