In September, 1955 Emma Gatewood became the first woman to hike the entire Appalachian Trail alone, as well as the first person, man or woman, to walk it twice, and three times. Grandma Gatewood, as reporters called her, started her first hike along the trail after telling her family she was going out for a walk. The next anybody heard from her she had hiked the first 800 miles of the 2,050-mile trail. Ben Montgomery, enterprise reporter for the Tampa Bay Times and founder of the narrative journalism website Gangrey.com, scoured Emma Gatewood’s diaries, trail journals and correspondence, and interviewed surviving family members and people she met along her hike, to unveil the story behind this 67-year old grandmother and her journeys. He talks with us about his book, Grandma Gatewood's Walk: The Inspiring Story of the Woman Who Saved the Appalachian Trail.
