Once famous as a Kansas "cow town," Abilene in 1867 was the terminal point of the Kansas Pacific (later Union Pacific) Railroad and the nearest railhead for the shipment of cattle brought north over the Chisholm Trail. The number of cattle shipped east from here between 1867 and 1871 has been estimated at more than a million, and often 500 cowboys were paid off at a time. City marshals Tom Smith and "Wild Bill" Hickock brought in law and order in the 1870s. Today, Abilene is a wheat center, perhaps best known as the boyhood home of Dwight D. Eisenhower.
