| <1> | Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Saint Clair) to Point B.Our distance measurements begin at a specific point in Saint Clair. The point we use is located at these GPS coordinates - Latitude: 38.3490, Longitude: -90.9882 In this case, the coordinates for Saint Clair have been provided by the Geographic Names Information System (GNIS). |
