Is International Falls anywhere near Frostbite Falls?
(Moose and Squirrel reference)
I think they’re both in Koochiching County, not far from Moosylvania, Bullwinkle’s family territory.
I would surmise that the Rocky and Bullwinkle script writers couldn’t come up with a more creative (and humorous) name than Koochiching County, where International Falls is actually located.
