If you’re not going to brush your teeth (hey, we’ve all been there—road-trip yuckmouth is just part of the deal) then you at least need to brush the holds. “Why?” you ask. “I mean, doesn’t someone come along and clean them each night?” Well, not really. That someone is us, and it’s up to us to take care of the cliffs and mountains where we play. Part of that is brushing off our excess chalk and that left by others. It makes the holds easier to grab and keeps the rock clean for you and for the next climber.
