Hogs used to walk to barns and markets rather than ride in double-decker trailers and snooze in air-conditioned barns. Modern confinement systems, 18-wheelers, and hydraulic carts have relegated hog driving to a lost art, and swine drives are only farrowing-house conversation topics. However, a couple generations ago, farmers moved hogs the old-fashioned way. They drove them. Hog drovers have gotten little attention from historians, novelists, and TV producers in painting romantic pictures of frontier agriculture. They’ve concentrated on rope-smart cowboys trailing herds of white-faced cattle. Hog drovers didn’t get much glamour. They wore bib overalls and walked, but some of their roundups were colorful and impressive.
