Having returned from and awesome December trip I thought I would weigh back in with my experiences.
Stuff I wish I had brought (or at least been more prepared with).
A "Daytripper" box: I haven't had time to read back through the regs, but I don't remember it. The (very very strict) ranger who did our check in wanted to see an undisclosed number of wag bags and supplies for hikes, preferably in a "daytripper" kit. We scrambled to find enough...he never did tell us how many we needed. Thanks to Gordon from Nebraska for bailing us out by lending us some of his supplies.
waterproof socks: There were days I didn't want to wear my drysuit and neoprene socks didn't cut it in the temps we had. Wearing splash gear on days without big water would have been a lot more pleasant with dry feet.
a better waterproof camera: I was solo in my boat, so getting the DSLR out while on the water wasn't something I wanted to do, and my gopro doesn't take great stills.
more warm hats: they get wet and my poor bald head gets cold.
more liquor, less beer: cocktails were much preferred over beer, at least on this trip.
a better gopro mount system: Helmet mounted gopro's make even grand canyon rapids look flat, videos I made just don't do them justice.
less of almost everything else. I (we) had too much food. I had too much extra cloths (especially layers and outerwear), we took 5 full sized tanks of propane and finished 1 and used part of 2 more.
my fucking knee braces: missed a couple of great hikes cause my oft-repaired knees got sick of carrying my fat ass up (and especially down) steep rocky trails.
better cold-weather rowing gloves: nothing to add to that
