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- Roan Hill) to Point B.Our distance measurements begin at a specific point in Roan Hill. The point we use is located at these GPS coordinates - Latitude: 36.3051, Longitude: -82.3457 In this case, the coordinates for Roan Hill have been provided by the Geographic Names Information System (GNIS).
