Longhorn Bull with a real bad attitude, out in the Wichita Mountains in Oklahoma !

Man this bull had a real bad attitude. He got aggressive with every other bull that was near him. None of the other bulls would challenge him. They would stand still and let him throw a fit. He was throwing sand around with his hoofs and horns. And he sure got very close to my vehicle. I was a afraid he would attack us, he might would have thought my vehicle is another bull, cause it is red. So we took off when he got this close as you can see on the end of the video. Does anyone know why they drool so bad ? Those bulls are located in the Wichita Mountains Wildlife Refuge !
