In 2004, Scott Rogers, 35, became the first above-the-knee amputee to hike the entire Appalachian Trail. Rogers lost his left leg in 1998 when he accidentally shot himself, but he says the accident made him stronger. He now gets around with C-leg, a prosthetic leg and foot that's driven by hydraulics and controlled by microprocessors that monitor his movement to create a stable gait. He says his kids inspired him to achieve his dream of hiking the AT, and he was further motivated when he met Lane Miliken, a 9-year-old amputee who'd read about Rogers' journey. Rogers, who was known as "One Leg" on the AT, dedicated his hike to the boy. Although his journey was challenging — several times he had to resort to crutches which made him "really feel handicapped" — Rogers is proud of his accomplishment. His advice for AT hikers? "Do not be so concerned with how many miles you cover in a day. Concentrate more on the smiles."
