I know a guy who got a ticket trying to catch crawdads, he had a piece of bacon tied to the end of his fishing rod with no hook but since the water he was trying to catch crawdads from was closed for spawning fish he was written up the cop told him if he was using a trap or just a string with the bacon on it he wouldnt of gotten a ticket. I think a lot of times it depends on what officer approaches you and whether or not he has had a bad day.
