What explorer had the greatest impact on history?

In 2019 Will Grant embarked on a 142-day, 2,000-mile horseback journey from the Pony Express stables in St. Joseph, Mo., to trail’s end in Sacramento, Calif.

William Frederick Cody (1846-1917) led a signal life, from his youthful exploits with the Pony Express and in service as a U.S. Army scout to his globetrotting days as a showman and international icon Buffalo Bill.

Texan Sam Privett, the colorfully nicknamed proprietor of Booger Red’s Wild West, backed up his boast he could ride anything on four legs.

Steve Friesen, the former director of the Buffalo Bill Museum & Grave in Colorado, assesses what has been written and filmed.
