One time somebody's bull showed up at a place where my friend lived. It had some fields but mostly a lot of dense mesquite brush along a river. Some cowboys showed up with a trailer, unloaded their horses, found the bull, hazed him around trying to throw ropes then bull went into the thorny mesquite. They left and came back with more cowboys and some dogs. Yelling could be heard, dogs barking, sound of brush popping and breaking for quite a while. Then, there went the bull swimming down the river around the bend out of sight. I don't think they ever caught the bull. It was quite a show.
