A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Boise City) to Point B.Our distance measurements begin at a specific point in Boise City. The point we use is located at these GPS coordinates - Latitude: 36.7296, Longitude: -102.5130
