Our distances are not driving distances, but are calculated as a 'point-to-point' distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Mount Airy) to Point B.Our distance measurements begin at a specific point in Mount Airy. The point we use is located at these GPS coordinates - Latitude: 36.5467, Longitude: -85.0838 In this case, the coordinates for Mount Airy have been provided by the Geographic Names Information System (GNIS).
