Interesting concept, however, being the overlanding curmudgeon that I am and since I depend on no digital mapping tools, I leave breadcrumbs. Actually, my wife is amazed at how well I remember where I have driven before, sometimes years later. We were recently out with a fellow traveler that lost his mind because his GIA app crashed. We were out ahead about 15 minutes, and he got on the radio freaking out about which way to go. Hmmm, there was only one way to go and that was to stay on the main track. My advice to all newcomers to this hobby? Learn to use paper maps, dead reckoning, and seat of the pants navigation. Then enjoy enjoy your other hobby and the luxury of digital navigation and tracking.
