Man walks 2,660-mile trail, takes selfie every mile to prove it
Over the course of five months, Andy Davidhazy hiked the Pacific Crest Trail, a 2,660-mile walk that began in Mexico and snaked up the West Coast. He took a selfie at every mile, and by the time he reached his destination in Canada, he was 50 pounds lighter and completed what he calls an "unambiguous challenge."
