Mary Meletiou learned to ride a bicycle on the quiet streets of Burlington in the 1950s. Later she would go on a 2,000 mile bicycle ride from Greensboro to Denver. In 1974, she went to Raleigh to promote bicycle touring in North Carolina. There were no bicycle routes at that time. Meletiou, an economic major at UNC-G, had also studied cartography. She developed the state's first bike trail, the 700-mile Mountains to the Sea Trail. Today the state's extensive Bicycling Highways System consists of nine trails, including the Ports of Call, the North Line Trace, and the Cape Fear Run. North Carolina's bicycle trails program has received national attention and served as a model for other states, including Colorado and Tennessee.
