I don't support the placement of bolted anchors on the Passport buttress! I don't understand the neccessity. Anyone competent enough to top-out this route should have the planning and rope skills necessary to get off using existing natural protection or a pre-set tyrolean.
Placing a half-way anchor down in the chasm may make some sense. But a bolt anchor on the top of the pinnacle is ridiculous. There are obvious natural bollards.
Neil - please do NOT use MY drill for this purpose.
Stop trying to tame all the wild places. You can climb in the gym if you want convienience.
