i left on the 31st, musta been marcus and christian who left on the 1st or 2nd.
i didn't do the main vein, but i imagine it goes very very fast and you can get off before dark. lane and I left the cabin at 9:30 for spying and flying and it has a 2+ hour approach with many pitches and we managed to get off before dark, so if you got up before 8am you should be fine. warning, do this on a cold, or cloudy day, w/o much wind. the top pitch gets baked as does the top of the mtn that feeds into the climb.
