Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Merrimac) to Point B.Our distance measurements begin at a specific point in Merrimac. The point we use is located at these GPS coordinates - Latitude: 37.6354, Longitude: -82.2160 In this case, the coordinates for Merrimac have been provided by the Geographic Names Information System (GNIS).
