I was in the Canadian Rockies with a friend, and we were starving for protein, so we started eating ground squirrels. We used your typical Boy Scout trap, where you put food under a pot and a rock on top, and you lift one edge with a stick. When the squirrel goes in, you pull a string on the stick. But then how do you get this pissed-off squirrel out? Well, you put white gas around the pot’s edges and light it, and that sucks all the oxygen out of the pot. Wait a minute or two, lift the lid, and there’s a dead squirrel.
