Richard,A few years ago my wife and I were driving down the coast and saw a herd in a field so we did the dumb tourist thing. We parked the car and walked over to about 25 yards from the herd. I told my wife not to go any closer, I was going back to the car for my smokes. When I got back with a burning cigarette one of the younger bulls looked over at us and started making some weird noises. I told the wife we should go back to the car because he was acting funny. When we were almost to the car the young bull came running toward us. I don't even remember how we got into the car it happened so fast. He stopped a few feet away and just paced back and forth until we left. I wonder if it was the cigarette.
