Our distances are not driving distances, but are calculated as a 'point-to-point' distance starting in Aurora. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Aurora) to Point B.
Our distance measurements begin at a specific point in Aurora. The point that we are using is located at these GPS coordinates - Latitude: 59.6833, Longitude: -151.1000 [Map]. In this case, the coordinates for Aurora have been provided by the Geographic Names Information System (GNIS).
