1860 Apr 3, The US Pony Express mail system began when one horse and rider carrying a bulging mail pouch began the 10 1/2-day run from San Francisco, Calif., to St. Joseph, Mo. Riders left St. Joseph, Missouri and Sacramento, Ca., at the same time. They averaged 12 mph over 75-100 mile segments between 153 (190) change stations. The freight company of Rus-sell, Majors and Waddell began the service. The enterprise failed after only 18 months, how-ever, due to mounting financial losses and competition from the ever-expanding telegraph net-work. Donald C. Biggs (d.2000 at 72), prof. of history at SF State, later authored "The Pony Express: Creation of the Legend."
