Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance that stretches from Flat Rock. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Flat Rock) to Point B.
Our distance measurements begin at a specific point in Flat Rock. The point that we are using is located at these GPS coordinates - Latitude: 34.7698, Longitude: -85.6944 [Map]. In this case, the coordinates for Flat Rock have been provided by the Geographic Names Information System (GNIS).
