Dave Cox has always been an outdoorsman, but has never undertaken any trip as long as this. He will turn 70 on the trip which will take him to Maine and then back to the Carolinas.

The Appalachian National Scenic Trail, generally known as the Appalachian Trail or simply the AT, is a marked hiking trail in the eastern United States extending between Springer Mountain in Georgia and Mount Katahdin in Maine.[2] It is approximately 2,184 miles (3,515 km)[a] long. The trail passes through the states of Georgia, North Carolina, Tennessee, Virginia, West Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, New Hampshire, and Maine. The path is maintained by 30 trail clubs and multiple partnerships,[3] and managed by the National Park Service and the nonprofit Appalachian Trail Conservancy.[4][5] The majority of the trail is in wilderness, although some portions traverse towns, roads and cross rivers.
