Well, if not fun, at least interesting and memorable.
Our troop made boats one year, and then in the next year we took those boats down the Sacramento river, from the end of the rapids at Redding, to the public launch ramp in Sacramento. A much longer trip than any of us had anticipated.
The boats were wooden kayak-looking things, with just enough room for one person in each. We used our duffel bags as seat cushions. The first thing that happened was the loss of our supply boat. Everyone had just assumed that we could just tie it to the stern of one of the other boats, since we were essentially just floating along with the current, but on the third day it got sideways to a gravel bar in a fast moving part of the river, and was broken to bits. Then we had to salvage the grub, and distribute it to all the rest of the boats.
Immediately thereafter, we all recognized that it should have been tied between two of the boats, but hindsight is usually 20-20.
My sons’ troop burned down one of their tents last year.
