I do not know Mr. Sullivan. I have seen some of his videos and they are entertaining. My Momma always taught me that if I could not say something nice, that I should just say nothing.
I was always taught to approach a downed buffalo from the tail end and not the head, in case it did regain its feet. I have seen a dead buffalo get up and attack the hunter (an acquaintance of mine) and the PH after having been supposedly killed. It happens. But, charges by buffalo are statistically not that common. I find it impressive that Mark's clients encounter so many instances where the wounded buff does charge. Why is that?
Mark's skill at arms with his doubles is impressive and that is about the nicest thing I can say. I would not want to hunt with him. Not my style. If he wants to kill buffalo, he should be paying the trophy fee. When I hunted buffalo, I did all the shooting. Not because I told the PH not to. On the contrary, I told him that if the buffalo threatened him, the trackers or myself, he should shoot if he had a shot and I would do the same. He did not need to shoot and the buff did not charge as most do not. Are they dangerous?, yes, they can be. Can they be provoked? absolutely. If that is your thing, knock yourself out. Just not for me. Have a good-un Sir.
