Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Sunset) to Point B.Our distance measurements begin at a specific point in Sunset. The point we use is located at these GPS coordinates - Latitude: 36.5317, Longitude: -85.1602 In this case, the coordinates for Sunset have been provided by the Geographic Names Information System (GNIS).
