Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance starting from Kings Hill. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Kings Hill) to Point B.
Our distance measurements begin at a specific point in Kings Hill. The point that we are using is located at these GPS coordinates - Latitude: 34.1340, Longitude: -85.8189 [Map]. In this case, the coordinates for Kings Hill have been provided by the Geographic Names Information System (GNIS).
