Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance starting in Homer. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Homer) to Point B.
Our distance measurements begin at a specific point in Homer. The point that we are using is located at these GPS coordinates - Latitude: 34.2634, Longitude: -85.9072 [Map]. In this case, the coordinates for Homer have been provided by the Geographic Names Information System (GNIS).
