To tell the truth, I know nothing about the science or economics of varmint bounties and I was just flapping my jaws er, I mean, offering my opinion.
I recall stories about the rattlesnake roundups..bounties were paid...
But it seems to me that where you have this obvious problem..a dangerous, destructive feral hog population...and lots of hunters...there has to be an economically driven solution..
maybe the state, and the most affected counties..contribute some funds...maybe charge a fee for the hunt permit..but also pay bounties, prizes, maybe have drawings...maybe a reality TV show....I'mm sure one of the hunting themed cable nets would buy into it...
