You know at Nuges place in Michigan you're hunting animals that can't be found running outside a fence because they are not feral hogs. He's got Russian or European line of boars. There's a difference. Any other boar hunt is a razor backs or feral hogs. Nothing wrong with shooting either just some good bacon. Personally Russian boars make a great trophy too.
I look at high fence if it's legal and the animals are capable of running away then it's a hunt. I have only hunted animals I can't hunt in the wild very easily like exotics. Go have fun.
