On the Appalachian Trail, an unexpected gift can make all the difference. A bottle of water. Something to eat. A little help when the miles become too much. Hikers call it "trail magic." Matthew Calder could certainly use some. Alone after his girlfriend’s early departure, he’s determined to finish the hike they started together. Then his backpack vanishes, taking his food, shelter, and means of calling for help. By nightfall, the supplies someone has left behind feel like a miracle. But another day passes without a single person on the trail. Then another. And whoever keeps leaving those gifts seems to know exactly what Matt needs. Listen on YouTube:
