| <1> | Our distances are not driving distances, but are calculated as a '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- Poolesville) to Point B.Our distance measurements begin at a specific point in Poolesville.  The point we use is located at these GPS coordinates - Latitude: 39.1423, Longitude: -77.4101        In this case, the coordinates for Poolesville have been provided by the Geographic Names Information System (GNIS). |
