Mike Libecki is obsessed? Addicted? with expeditions. He’s made 70-some journeys that would each be once-in-a-lifetime for 99 percent of the rest of the human population. A climber, explorer, thrill-seeker for whom nothing is too high, exposed, cold, or wet to try. This time, he was stymied by a devilishly difficult rock spire he’d been salivating over for 5 years. But a trip is always a success when you get to return home to your family.
