Describe how changes in transportation have affected communication over long distances.

There have been numerous ways that transportation has affected communication over long distances. The postal service has changed significantly over the years. When the post office first opened. The mail was delivered slowly, by horses, carriages, or even ships if overseas. Over the years, mail is delivered overnight by airplanes and semi-trucks. Before transportation, it could months or even years to get a piece of mail, depending on where it being delivered. The opening of the transcontinental railroad also helped to change communication. People could then get to places to see and speak to family or business associates without having to take dangerous methods of transportation. Otherwise, the only way the people could have had any way to communicate would have been by the slow mail system of those days.
