Very little is required to present myself as a cyclist. First, I need to decide which of my two bikes I want to ride. Secondly, I need to take the chosen bike outside. Next, I straddle the bike. Finally, I go nowhere in particular and then return!
So much more is involved in climbing. I’ve pulled on plastic for ten years, climbing only indoors because getting to the crags requires a car. To go to the climbing gym, though, I still need to find someone to accompany me. Preferably somebody who likes me, but most importantly, somebody who I can trust to not drop me. Then, this special somebody needs to have a work schedule that does not conflict with mine. I need to know only one type of knot, the figure eight.
To climb outdoors is an even bigger challenge. Other than a car, I would need at least one climbing partner who knows how to build and clean anchors, as well as lead climb and belay. I would have to get used to reassuring my friends and family that, yes, I will be careful. There’s a surprising amount of knot tying knowledge needed.
