I've got a friend who manages a large farm in Georgia for a semi-absentee land owner and one of his regular jobs is to help keep the wild hog population in check. The hogs, hoglettes and hogettes regularly damage fences, crops and just about anything else you can name. On the positive side, they are delicious when cooked properly. As far as attacks go, like most wild things, they pretty much stay away from humans if you leave them alone. 8T
