Wow, the trip sounds awesome, T-Al--I love these split vacations every now and again--they make the joint trips even better!
And I'm with Deserat--that is a lot of stuff! Hey, what is this ultralight backpacking guide you mentioned? I need all the help I can get to reduce DH's propensity to pack too much! Me, I focus on underwear, pretty much everything else can be worked out on site/en route!
