Our local guidebook author recently introduce a co-author of a recent Yosemite guide to climbing at Pinns. It was a setup, an awful pitch that "had to be climbed". His comment was something like "That is the worst climb I have ever done, no, in fact it was the worst pitch I have ever done." For some strange reason he was smiling as he said it.
Fortunately the first-timer ended up on better Mud routes as the day progressed.
