Manfred, we should probably just do it again next September... :)
Would you do anything differently if you did it again? At the time, I thought it would be nice to go a little slower so that we could hang out in the beautiful places for longer. But everywhere was beautiful, and looking back now I enjoyed that we got to see so much in such a short time.
In terms of gear, I don't think I would change anything. I would bring a Tenkara rod though :) I would definitely bring less food, 1.5 ppppd instead of 1.7. And I would bring about half as much TP, sunscreen, etc. Those two things would probably have saved me 3 lbs coming out of Road's End.
