Down at Suicide Rock, across the valley from Tahquitz, there is an old aid line called "The Pirate," a really really thin crack. It has since gone free by climbing the pin scars, only 5.12 if I recall, but back in the late 70's it was still an aid route. We were messing around at the bottom, joking about climbing it, playing with the pin scars. Now, most of this crack was in the knifeblade size, but the pinscar in question would take the tips of two fingers, not quite to the first knuckle. I'm standing there, fingers in the scar, and it screams at me. I jump back, and this angry little bat face wriggles out of the hole and flies away. I'd had no idea they could occupy such a tiny space...
