Then the time lag between the climbs became a problem. I started eyeing skyscrapers, telling myself that I would just plan the route up but not climb it. Right. To get up a rock wall you study the outside, trying to pick the best footholds and handholds, guessing where you’re going to encounter problems so you have the right equipment with you to get around them. To climb a skyscraper you have to know the inside as well as the outside. (Which is where I screwed up on my last climb.)
