EDIT (2005): Billy the Kid is a harder variation to Garrett's Revenge that breaks off to the right at the roof, and above the Ashtray belay ledge. The crux is the roof and has a difficult clip. Then the difficulty eases immensely above. Cruise up the face, pass some huecos, and belay on a ramp (Metolious hangers).
EDIT: 15 bolts.
