To find this route, head up to the mural wall and turn left. Hike for approximately 100 yards until you turn right into a pretty big corner system. On the right wall there should be two bolted lines (left one is Tuna! Tuna! Tuna! and the right one is Soluble Fish, both are 11b/c). On the left hand wall will be a bolted route in which a kind of gnarly, soft looking crack will be on the right side. This is HNB. Cautiously crimp to the first and second bolt. Here you will be faced with a choice. The straight up method is fairly thin, but aesthetic. Most people head over to the crack on the right, which also provides enjoyable climbing.
Moving right into the crack makes the top section of the route easier... but kind of awkward to step left for clipping.
Climbed there the first week in November. This corner was in shade all day with some sun on this route and to its left. Perfect temperature for t-shirt and light jacket.
