Hey Erik--
BTW, I've hiked the North Dome Gulley, in the dark, mind you, and it is no cake walk. The rap saves at least an hour over the hike, the added bonus being you avoid traversing across the wet dirty runnout slab at the end that's far scarier than the rest of the climb.
All this aside, the point I was trying to make was it's better to wait until your feet touch the ground before you toke up. The crux of many climbs is in the decent.
Don't smoke crack on Liberty Crack, but if you're just clipping bolts on Pot Ash Road....
