Two comments: Did you walk around the Trail Camp pond to the west end to the water inlet? I've always dipped my water there and never treated it. I am wondering if, in the cold, the inlet was not flowing. (Even so, I think I'd have just dipped and called it good.)
#2: As for which was harder... how many months did you and your dad train for that marathon? And how many for Mt. Whitney? ;)
