You are hunting a species that with no natural eneimies, therefore no way to control there numbers, so i say to each there own.
It realy depends on the place i am hunting, some places i will lose if we turn pigs out, some we can cut and turn loose, and if i have people asking for meat i will call them to come get the meat. But the way i see it if you are going to hog hunt you have to be willing to do all that comes with it. JMO
