They tear up for roots. Saw one farm where they plowed up 150 feet getting fresh planted seed for corn. They roam neighborhood tearing up flower beds and lawns. Think of them as 200 pound rats born pregnant.
I can't see us in the south ever running out of hogs to hunt. Daylight or dark with whatever type of firearm a guy decided to use....there is always a way to find more of them. I started keeping track of the ones I shot on one piece of property about 10 years ago and I'm at 797 of them so far.
