The stretch of U.S. Route 15 in Virginia's Piedmont passes through some of the most beautiful and historic land in the United States. Also known as the James Madison Highway, the route links land north and south of the Mason-Dixon Line and follows the same general path used for centuries by Native Americans, colonists, armies, and presidents. As postcards and automobiles became popular in the 20th century, travelers could find postcards for the towns of Leesburg, Warrenton, Culpeper, and Orange. They tell a story of great people and great events, as well as providing a glimpse of daily life for those who lived along this byway.
