I watched Black Death and Use Enough Death and I learned a few things about different calibers, bullets and stopping power. As far as Mark Sullivan's ego, well I live in southern Alabama and we got some hunters down here with ego's as high as friggin Mt. Everest. I can live with that plus the man broke no laws which is more that I can say for the other hunters with big ego's. When Mark is gone we'll probably all realise that he wasn't such a bad guy after all. We can still learn something from him even if we don't like him. Just saying.
