| <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- Roddy) to Point B.Our distance measurements begin at a specific point in Roddy.  The point we use is located at these GPS coordinates - Latitude: 39.6407, Longitude: -77.4019        In this case, the coordinates for Roddy have been provided by the Geographic Names Information System (GNIS). |
