Growing movement said not to work, resulting in disappearance of wildlife and spread of disease-

Hunting and eating feral hogs less likely to cause furor-

I enjoy editing this on-line newspaper, but one of the things I don’t like is the never ending debate over whether hunting is right or wrong. It can never be settled and leads to disunity among those who use the outdoors and wildlife. I do […]
