He turned in over 10,000 fish! What are the odds this guy has a pond on his property where he raises these fish for their bounty? $100,000 is pretty good pay off.
Gotta be gaming the system some way- - - - -electric fishing, maybe? Call 'em up with a crank telephone, or use a neon sign transformer with wires hung off both ends of his boat, possibly?
That reminds me of the city that had a bounty on rats, and gave a cash reward for each rat tail. After a while there were thousands of tailless rats running around making more rat babies. I guess the catch here (pun intended) is they have to be over 8 inches. Maybe it takes a long while for them to get that big.
