Today's cowboy plants one boot firmly in the traditions of the Old West and the other in the world of modern technology. Beginning in the 19th century, the era in which the American cattle industry boomed, we examine cowboy technology. Learn how North American cowboys converted saddles, ropes, spurs, and other equipment originally developed by the Spanish, into tools of the trade perfectly suited for the developing cattle industry. And see how the invention of barbed wire revolutionized the cowboy's world. Step into the 21st century with today's cowboys who use computer chips, retinal scans, DNA evidence to round up cattle rustlers, and high-tech digital-imaging devices to aid in shoeing horses...and ride ATVs as often as their horses. In the world of rodeo, witness today's cowboys as they utilize advanced theories of genetics and artificial insemination in an attempt to breed the perfect bucking bull.
