From Frostbite Falls, it's across a couple of the Great Lakes and portage through downtown Chicago, as the Great Canoe and Leaky Retrofitted Airplane Race is on! It's stroke-stroke-stroke and bail-bail-bail as the pursuit continues down ever more tiny waterways!

Will it be Two for the Ripsaw, or, is it Good-bye, Mister Chips?
