I went once with my Uncle in South Carolina. We hunted in thick cover in some swamp and lots of briars. I used a .44 mag rifle. I didn't have any luck. The dog we were using had one cornered and we could hear him snorting but we couldn't see him. After a couple minutes the dog stopped barking and the hog left. The dog still had 70 stitches in his stomach from an encounter with a boar a few weeks earlier. It is very unusual for the dog to back down but we figure that's what happened. I guess the injury from the previous boar was still fresh in his mind. It is a lot of fun.
Heck that would be motivation for me to not mess with a big boar. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
