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 drawn from Point A (ie- Gary) to Point B.Our distance measurements begin at a specific point in Gary. The point we use is located at these GPS coordinates - Latitude: 37.3659, Longitude: -81.5473 In this case, the coordinates for Gary have been provided by the Geographic Names Information System (GNIS).
