In Arizona and other places in the Southwestern desert, rounding up cattle is not an easy job to accomplish. The cactus, rocky ground and thick thorny brush can create some real obstacles for the cowboys. An experienced hand is aware that the cattle know if they get into the brush it is almost impossible to get them out. The cowboy is after a steer to rope him before there is a chance to get away. Bill has personal experience with this on local desert ranches he has visited.
