Tarahumara etiquette. Before approaching a Tarahumara cave, you have to take a seat on the ground a few dozen yards away and wait. You then look off in the opposite direction for a while, as if you’d just happened to be wandering by with nothing better to do. If someone appears and invites you into the cave, great. If not, you get up and go. You do not go walking right up to the entrance, the way Salvador and I had. The Tarahumara like to be visible only if they decide to be; laying eyes on them without invitation was like barging in on someone naked in the bathroom.
