Paddle to the amazon; Paddle to the Arctic

I recently finished reading Paddle to the Acrtic, and re-reading Paddle to the Amazon. These are amazing stories. In 1980 a man and his two sons embark upon a truly bold adventure. The plan: canoe from Winnipeg Manitoba, CANADA, all the way to the mouth of the Amazon River--completely under their own power. It takes them two years, countless encounters with extreme danger, and one son heads home early, but they do it! About a decade later, as if to prove that he is indeed complete and totally (and wonderfully) crazy, that same man, sans sons, attempts to paddle the Northwest Passage (Churchill Manitoba to Tuktoyaktuk NT) and though it takes him a few seasons, and a few friends, he ultimately awakens to find that he has pretty much propelled his half-frozen-amputation-requiring-carcass to his destination. Best of all, the book is written in diary format, and partway though he starts recording GPS coordinates with each entry! Reading the book while connected Google Earth makes you feel like you are right there, only warmer.
