hogs are a problem only if they are costing somebody money. In this case, it's the farmers and ranchers. the cooperative of farmers and ranchers should be looking to put a plan in place to eradicate the damn things, and then pay for that plan. When there is money involved, THEN you will see the proper, massive slaughter of feral hogs, as opposed to the entertainment of people via the many retarded ways people can come up with to pursue them.
I guarantee you, technology exists from military, space, and commercial industries to put together systems that would exterminate massive numbers of these damn things effortlessly.
