Brothers Wild: Timmy and Sean O'Neill

Brothers Timmy and Sean O'Neill are not only a tight climbing team, but they have broken new ground for paraplegic climbers. Sean is paralyzed from the waist down after an accident years ago, but he and Timmy are scaling new heights. They climb the 3,000-foot wall of El Capitan in Yosemite, as well as a thousand-foot wall in the glaciated Ruth Gorge of Alaska.
