I've lived on a working farm my whole life- if there is a loose bull around, get out of the way unless you have large caliber high powered rounds. I watched one literally shove a barn over one day. They are freakishly strong, fast, agile, and just plain nasty. My family still tells the story about one before I was old enough to remember- the bull got out of his corral and before they were able to tranquilize him he attacked one of the horses (the horse was curious about the new funny looking horse in the field) and killed him. Yeah. Don't mess with the bull.
OK, random barely relevant rant over.
