Those tagged and/or trained to lead the sounder to the trap are called judas pigs.
A local gets paid to harvest them. How feasible is it for an outsider to find a landowner with a hog problem and gain access to shoot them? Trust issues? Liability ?? I get the reluctance to tell every tom, dick, and harry "come onto my property and shoot them".
I ask because hog hunting is on my bucket list. I've been researching it for several years. Seems the only option for me at a reasonable cost is to hunt public land. But, I wonder what a night or two in a local drinking establishment in an area with a high hog population might uncover. Maybe a "come on out!".
I have no desire to pay an outfitter $500+ when I can pay an IL farmer about 50 cents per pound and "hunt" in a 10 by 10 pen.
The whole deal is just difficult for me to wrap my mind around. Southern USA has a hog problem. Hunters are willing to help alleviate the problem. But, landowners/government unwilling to make it possible. Seems like a CRP/WIHA/WIAH.... solution may help.
