The whole "hogs charge" thing is blown out of proportion. in my 30+ years dealing with these creatures (bow hunting, trapping, and knife hunting) I have never had a single hog charge. They tend to want to run, and sometimes it is in your direction. They cant see well. I usually carry a pocket full of rocks with me when I am deer hunting. When I come up on the hogs, i throw rocks at them to get them to leave.
