The horses are descendants of Joe Kirk's good Quarter Horse bloodlines that were shown several years previously before he upgraded to running horses. The ranch keeps 25 to 30 brood mares with 2 to 3 stallions to produce good quality horses for use on the ranch. Calvin Peters has been the Quien Sabe manager for 20years. He makes every attempt to include everyone in ranch activities. Employee children are given a horse and encouraged to attend working when possible.
Wives often help with branding and other types of work.
The Quien Sabe Ranch takes pride in its people, its cattle and its horses. Guthrie Boyhood friends from Mississippi, Eugene Williams, a sales manager for the St. Louis-based Hamilton Brown Shoe Co., and D.B. Gardner, a Texas surveyor, established the Pitchfork Ranch in 1870. Gardener purchased cattle from South Texas to begin the ranch. The herd already wore the Pitchfork brand so he simply named the ranch after the brand. In 1883, the ranch was incorporated with the principal stockholders being the Williams family in St. Louis.
