NO MOBILE PHONE OR INTERNET SERVICE IS REQUIRED to use this app. There are more than 20 alternate routes plus 3,800+ waypoints, including comprehensive water source information. The free section includes portions of the two routes from the Mexico-U.S. border: the Crazy Cook route to Lordsburg, and the Columbus Gila route to Deming. The remainder of the trail is available for purchase by state: New Mexico, Colorado, Wyoming, Idaho/S. Montana (to Johnson Lake) and N. Montana. Each of the 3,800 waypoints includes a detail page, providing further details about that particular waypoint.
