I've killed hogs in Tennessee and Alabama. None hunted me, Most ran at the scent of humans. The hogs I've encountered were smart, tough, and wise to the ways of hunters.
All bets may be off when a wounded animal begins to run. He may come at you.
I use game cams at our hunting lease in Alabama and have many photos of what appear to be European type boars. After the boars escape and breed with our feral hogs a lot of the next generation pigs no longer look like a domestic pig. We've got some hogs that are tall and lean with long hackles on their back. These look just plain ole mean... Many of the places that advertise hunting for Russian Boars are in reality letting you hunt Americanized feral hogs that may have some European bloodlines in their background. A lot of the hogs on our lease breed and inbreed and start to look like the European or Russian hogs. On our lease we have a few that look as big as a 4-wheeler, and lots of little squealers types too.
Some look European and some don't...
Hogs have taken over a lot of good Deer range, and eat all the acorns. Hogs have trashed some of our green fields and bedded down in the middle to be near the chow. Some of our best creek bottom land has been turned into hog wallows. I hog hunt year round, and we can't make a dent in the population.
Last summer I ran into a group of sows and small pigglets (about 20) that were trashing one of my deer feeders. I shot a sow and the rest scattered. (I was carrying a pistol, while I was carrying feed to one of my feeders.)
Game cams show many of the same hogs returning every night to check the feeders. Did I mention that hogs are very smart and learn as they go... Unlike a lot of our hunters...
