If you've heard of Justin Salas, you may refer to him as a "blind climber". You'd be wrong. He's a climber who happens to be blind, just like you're a climber who happens to have sight.
I had the opportunity to session with Justin at Tension Climbing, and it was fascinating to get to observe and be a part of his process, and talking through it with him was just as interesting. The tools that Justin uses to climb into the V-double digits are the same tools that we use, and the same ones that many of fail to cultivate.
We've got a lot to learn.
