In St Joseph, Missouri there is a museum devoted to the Pony Express. St Joe was the launching point for this short lived wild communication service. Young riders would gallop full speed, changing horses along the way to get to Sacramento with about 20 pounds worth of mail. Letters cost $5 each to mail. Very expensive for 1860. The Express lasted 18 months but is a well glorified part of the expansion West in early America. The completion of a coast to coast telegraph system brought the Pony Express to it final ride.
