As a young nation grew in size the need to communicate was important.

The Pony Express was important because they got mail to the east coast west coast In a shorter amount of time. This was important because sometimes mail would not reach it's destination for months.This had a big impact on politics and communications. Even though the Pony express lasted only a year it changed the way people were informed about the latest events.

From time beginning people have needed to communicate.  It is sometimes the most expensive aspect of any society and business.  Maintaining a forward movement of any purpose for human history has surrounded communication and transportation. 

Writing with pen and ink, be it a quill, was a necessity to any form of civilization.  During the day of The Pony Express, there were inherent dangers to making progress.  They were known and measured dangers and compensated with enough monies to make the 'risk taking' worth it.  The Pony Express would be replaced by stage coach and railroad.  As time went by and cities grew the dangers diminished and today the USA Postal Service is in danger with competition from private carriers.  A different danger, but, a concern just the same.
