Channel Catfish, Genl McOmish .... they grow pretty big too.
Edited to add: I think the technical term for what I was describing is called "Kanoodling" - and they had a debate on whether to have a fishing season for just that -pulling these fish out of their holes in the mud bank. . . iirc it was mainly around the Mississippi River area and probably the Lakes (Lake of the Ozarks and possibly Truman Lake - the Missouri River has been fairly heavily modified over the years by the Army Corps of Engineers -so I am not sure they do that there ... ) The things can sometimes get upwards of 2 meters long at times. Another form of fishing for the things is on something called Trot(t) Lines - usually done with home made fishing floats made out of things like big laundry detergent containers.
Mind you guys -the prior stuff is about as close "role playing" as I'm apt to get --- I look forward to the tournament you are planning.
Oh, and Blake, sir... the best redneck-ish thing I ever saw? Some guys made their own convertible with a reciprocating saw (think the commercial name is a Sawzall). . . yeh you bet I'm traumatized

. But I know you're perfectly correct in your assessment - they are everywhere.
