April 3rd is Pony Express Day

The Pony Express was a mail service delivering messages, newspapers, mail, and even small packages from St. Joseph, Missouri across the Great Plains, over the Rocky Mountains and the Sierra Nevada to Sacramento, California by horseback, using a series of relay stations. During its 18 months of operation, it reduced the time for messages to travel between the Atlantic and Pacific coasts to about 10 days. From April 3, 1860, to October 1861, it became the West's most direct means of east–west communication before the telegraph was established and was vital for tying the new state of California with the rest of the country.

The Pony Express was a mail-delivery system of the Leavenworth and Pike's Peak Express Company of 1859, which in 1860 became the Central Overland California and Pikes Peak Express Company. This firm was founded by William H. Russell, Alexander Majors, and William B. Waddell all of whom were notable in the freighting business.
