Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance starting from Sweethome. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Sweethome) to Point B.
Our distance measurements begin at a specific point in Sweethome. The point that we are using is located at these GPS coordinates - Latitude: 34.5765, Longitude: -93.5796 [Map]. In this case, the coordinates for Sweethome have been provided by the Geographic Names Information System (GNIS).
