For my money, there’s no better crash course in risk management than the documentary, Free Solo . To most, the thought of climbing 3,200 feet up the granite face of El Capitan in Yosemite National Park is daunting enough. But free-climbing it without any ropes is just pure insanity. Or is it? When Alex Honnold decided to climb El Capitan, it wasn’t just on a whim. He had spent more than a decade planning his ascent, logging dozens of climbs up and down the granite face, most of it roped in, so he could examine every crack and crevice.
