An airline pilot who had lived and flown all over the world, Ed Higginbotham wasn't going to stop traveling after he retired. So he set out to hike sections of the Appalachian Trail with a group of friends, and over the course of eight years, successfully section hiked from Georgia to Maine. After years in the sky and looking at America from 20,000 feet, he finally got a chance to experience America from an angle he hadn't been afforded after years of flying: close-up and on the ground.
