Short story: Dude loses iPhone on local trails at some point during his three hour mountain bike ride; dude uses my MacBook (he's a PC owner) to activate his phone's "Lost Mode,"; dude recognizes blinking blue light, representing his phone's location on a map, is on COD, near Century Dr.; dude tromps around woods, using my iPhone's map as a guide, and soon finds his phone laying in the trail—in tact and working fine.
