Great rugged anecdote from a VT friend who worked w/ the Montana forestry service for a while.
Various mid/western state forestry services get a subsidy to use the more expensive (and environmentally friendly) soybean/biodegradable oil as the bar and chain oil in their saws. Most every forestry service worker out there also packs a fishing rod and frying pan too. (you see where this is headed.....) He is out in the field taking dinner with these guys, only to see them tip their saws over, and pour oil from the reservoir onto a hot pan and start fryin away. Classic scene.
