A decade and a half ago I was hunting caribou in northern Quebec with a young guide whose name I've forgotten, but who was only 19 and tough. I had shot a caribou and we were on our way back to the boat, him carrying a tumpline pack that probably weighed 150 pounds. Not far from the boat he stepped into a bog hole and immediately sank up to his neck. That was as far down as he went, but he was in big trouble. I eased out on the bog on my belly, and we wrestled him out of the pack. Without that nailing him in place he was able to wiggle free of his boots, and then between the two of us, we got him clear of the mud. But if it had been just him, alone?
