In reply to antdav:
Take a dozen, as others have suggested, then when you get there count the number of bolts on each pitch and take a couple of extras. Also, at least one sling plus screw-gate krab to attach directly from the harness to the top bolts.
If you are new to this, make sure you thoroughly understand the safe way of threading the bolts or chains at the top of the pitch: the key points are that you should never be detached from the rope nor should your second stop belaying you until you are back on the ground. Think safety first!
