I suppose someone has answered this by now. The Wendago is also a legend in the Upper Peninsula of Michigan(check map).Marquette got 253 inches of snow one winter a few years back. Some people think the stories relate not just to the winters,but the forests themselves. We still had uncut forest when I was a child,with few roads. Opinion holds that this really related to cannibalism,which did exist during the worst seasons. Rick Curtis did a much more forceful,eery version of the song;this did not have the vocal demonstration at the end and was not as "pretty".He did always say he learned it from Dwain Story.
