This climbs the face right of "Casual Observer". The bottom has a few variations staying between the large chimney to the left and the crack of Ripoff to the right. A fun one is to start left then dyno to the huge ledge in the middle.
Either way, the technical crux comes halfway up and involves sidepulls, finger locks, and small edges for you feet. Numerous rests but still a nice pumpy, continuous line.
