Writing in chalk
Please stop putting the dreaded "X", "Bees" or "Snake" on the rock faces. Please be smart and conscious of others.
Stop putting tick marks on the rock unless you are going to brush them off when you are done on the route. This goes against the ethic of the area and in the eyes of the locals is the same as graffiti. Rock climbing is an outdoor sport and guess what lives outdoors? That's right, bees, wasps, snakes, and even bears! We all know they exist, no reason to write it on the walls.
