The Natchez Trace Parkway was the major road that was walked or traveled on horseback in the years up to 1801 when the US government widened it (to 8 feet) for use to transport the mail. It was a beautiful drive through the forests and cypress swamps of Mississippi and Tennessee. There are not commercial trucks allowed on the Parkway and the speed limit is 50mph. It was a very enjoyable ride. We took two day with stops at every historical marker.
