Throw in injuries after scrabbling through heavy northern forest. I've gone through a few dozen yards of that kind of shit and wouldn't want to go any further. Imagining endless swaths of it with no possible end in sight would be enough to end me. I too don't believe they had anything to do with the boat. They showed up in my end of the woods (north east Alberta) and got stuck on a trail. A guy my kid knows unwittingly pulled them out of the ditch and sent them on their way. I think they were just trying to "leave no trace" before they ended themselves. I would lay money the CBC is already working on the script for the TV movie.
