Being on board is super cool, and I understand the supplies deal. I'm just accustomed to being self-supported, and that doesn't bug me at all. Something like the HooDoo or Furnace Creek appealed to me, with drop bags and such.
Ah, yeah. For me that would be double anything I've done, so I wouldn't be willing to try it unsupported.
I do need to check the climate chart and see how the fall goes, because it could easily be too cold for my fingers then.
