I have the perfect example.. wife's uncle has a duck roost in ok that always holds ducks. tried picking up twigs one winter during pecan season and it almost killed me. Decided to furnish all the catfish for uncles birthday fish fry. Anybody wants to duck hunt on uncle's place they have to call me first.

Granted it took several trip to accumulate 75 lbs of fillets to feed his 60 or so family and friends. I had fun doing it and paid my way for the following duck season
