I actually believe that a bad bull is not as dangerous as a gentle bull. That is because you darn sure avoid a bad bull and always have an escape route. Whereas a gentle bull you are much more likely to turn your back on him and forget he is there. That being said the first time a bull looks cross eyed at me he has a one way ticket out of here. And I don't care how young he is or how well bred he is or how much money I have tied up in him. I have been face down in a pen with a bull in the middle of my back before and it isn't as much fun as some would have you believe.
