That was my world for 4 years. If the neighbors bull didn't tear through the fence, he'd simply jump. That bull was our "guest" off/on so many times, he was trained to come to me with a bucket. I was never so happy to see them FINALLY move the entire herd.That's many more chances then I would give. For us it's 'if you cross the river/creek you are owner of a one way ticket come fall'.
But who are we kidding, if not ourselves. If a bull wants to go he is gonna go, not much fence is going to hold him from doing so.
