An intro to climbing class is less about learning how to climb than it is about learning how to fall. Or rather, how not to fall — and if you do (and you will), how to fall without bone-breaking repercussions. That’s a good thing because once you’re assured that it’s OK to fall, that you won’t break your skull should you part with the wall, your confidence — a key element of climbing — will carry you to new heights. Literally.
