I love reading your trip reports, 100% entertainment. Cute that your kids are outfitted in Keens. We had Keens for our son, even though they are impractical for a barely walking toddler but they are adorable. Until you take a hard buggy portage and find out out at the end that he's missing one shoe. I kind of hope somebody finds the missing shoe, somewhere downstream of Nahma/Craig Lake, and posts a lost and found notice.
I appreciate how much time you must have spent planning, packing, and then getting stuff cleaned and put away just to make this trip happen. All that work and anticipation is almost as fun as actually being out there, in my opinion.
