Missouri outlawed sport hunting. They identified the major problem as idiots illegally transporting and releasing hogs so they could turn around and hunt them. So they decided to actually address the problem instead of the symptom.It will work, but I live in reality. It will NEVER even be attempted. One there are too many people that will lobby to keep it open. Two the amount of money to wipe them out with hired shooters/trappers AND keep them out will be huge and you would probably never get the proper funding.
That plan is literally the only chance a state has of wiping hogs out and keeping them out.
