Our distances are not driving distances, but are calculated as a 'straight-line' distance that stretches from Exum. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Exum) to Point B.
Our distance measurements begin at a specific point in Exum. The point that we are using is located at these GPS coordinates - Latitude: 33.5029, Longitude: -86.9333 [Map]. In this case, the coordinates for Exum have been provided by the Geographic Names Information System (GNIS).
