Funny side note. Last weekend I took my cert course for Swiftwater rescue. Unfortunately one of our guys way injured when he clipped a rock and split his knee open performing a rescue.
Picture, if you will, 12 students completely focused on the task of saving lives, and not a first aid kit in the group. They all got left at our vehicles nearly a mile downriver.
(for the record I now keep mine in an otter box in my PFD pocket)
When I was in grad school I got sponsored to go to UVa for a conference by a libertarian group (The Institute for Humane Studies) It was sweet deal, room, board, books and beer free for a week! All you had to organize for yourself was sex, and and if you couldn't manage that, you didn't deserve to get laid. I mean seriously, a bunch of 20 something libertarians on a vacation who have been given free beer and are brought together to study and party, who can't score under those circumstances?

My favorite memory is a lot like your group of first aid focused kayakers realizing no one brought an actual first aid kit.
One night, post beer, we were hanging out on the quad of UVa and watched a few coeds run down it naked to kiss the staue of Homer at the far end, which is apparently traditional. This was much to our amusement, as its a long quad and its terraced, so its uphill on the way back, and they were walking on the return trip (clearly being in shape wasn't a requirement for whatever sority they were pledging). Someone asked "Does anyone have a joint" ? The answer was no, because just like JC's S@R minded whitewater guys, none of us thought to to bring one. Thus we were left to watch pudgy sorority pledges walk naked across the campus Thomas Jefferson built in a state of cold sobriety. It was a bit ugly. We now know the answer to the age old question "How many libertarians does it take to get stoned"?" The answer is "None, the invisible hand will do it" I mean seriously, a dozen 20 something libertatians and no one has any weed? WTF? We all learned a hard lesson while watching those girls drag their asses across that quad.
