| <1> | Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Heads) to Point B.Our distance measurements begin at a specific point in Heads. The point we use is located at these GPS coordinates - Latitude: 35.8626, Longitude: -85.5941 In this case, the coordinates for Heads have been provided by the Geographic Names Information System (GNIS). |
