Climbing with Erik Weihenmayer

The blind adventurer has climbed the highest mountain on every continent, and he isn't done yet. On top of his climbing feats, Erik Weihenmayer has also kayaked the length of the Colorado river through the Grand Canyon and completed some of the world's most gruelling races. All already difficult feats for someone with a 20/20 vision, exponentially more so for one without, like him. Brent Crane interviews the inspiring figure for The Economist's 1843 magazine.
