good to hear your safe and sound.from my reading this seems to be a text book example of what can go wrong despite having the right gear and knowledge to make it right.some self induced pressures along with what seems at first to be a minor medical problem or pain, then a cascade of small errors that put you in the "drink".i think down hill skiers have a saying about the one last run of the day that maybe should not have been made.my only close call with hypothermia on a canoe trip was when i did the "i'll just push on to the next bay and a nice camp" when i should have pulled in to the first level spot and got into dry clothes and had a hot meal.most times it's not "nature" that kills us,it's us.
