The Four Sixes is not a relic, showpiece, or preserve. It's a working cattle ranch, some 290,000 acres of West Texas prairie carefully used. Here, men still earn their livelihoods on horseback, not out of blind adherence to tradition, but out of necessity. Across four generations, foremen have striven to nurture and restore, to leave a healthy range. That stewardship has produced some of the richest, most ecologically diverse grassland found on the Southern Plains today.
