I live on a large cattle ranch in the Northwest with my husband of 25 years and giggle when I hear you tell people that cattle have boundaries. It's true! And on the ranch, we have cattle drives. Picture an old John Wayne western where heโs riding his horse, herding cattle across the land. There are several hundred head of cattle, called a big herd, and lots of cowboys on horses, yelling things like, "hey cow," "yip yip" "hey hey, come on" and other whistles or sound to keep them together and moving in the right direction.
