I went on a week-long canoe trip once (as I'm sure many of you have also done, or something similar) - seven days, always wet, with four pre-teens having the time of their lives. We slept on the ground in a sleeping bag, cooked over a fire, used the bathroom behind or over whatever fallen tree we could find, bathed in the icy-cold river, and in general tried to stay upright and not lose our gear or food. We were sunburned, chafed and bug-bitten, but happy. About Day 5 we happened upon a riverside campground and canoe rental. With real flushing TOILETS!!! And HOT showers!!! And a LAUNDRY!!! It was absolutely Heaven for a few hours.
Our last night on the river was on a sandbar - at least the ground was soft for a change. We had eaten the last of our cheese, crackers, sardines and apples. Next day, just 1/4-mile from the takeout (ending point) - I could see it around a bend

- one of the kids was trying to smack the water with a paddle to scare the turtles off a log, and instead whacked the skull of another kid. Blood and general chaos ensued. But it was fine, slapped a towel on her head and paddled for shore, then hospital and stitches.
Ahhh.... fun times.
