I've saw quite a bit of this last spring. There would be a group of 5 or 6 fishermen with really heavy monofilament tossing out their line by hand using washers or nuts for sinkers. Finally I asked around and was told these folks probably didn't have fishing license and maybe not even American citizenship, plus they kept every fish they caught, legal or illegal. One day I noticed three gentlemen kicked their cans in and quickly climbed the bank and hightailed it out of Dodge. In about 10 minutes or so, a game warden came around checking license. He had checked mine a couple weeks earlier and remembered me. So I imagine I was given some accurate information.
