Together with WindsorSue, we have something new on the penultimate leg. They traveled by train on the Agawa Canyon tour that links to Sault Ste Marie and runs north, as I suspected in my post from yesterday.
Took notice that one of the new clips in the intro is of a silver train (high speed train in China didn't match) passing alongside a highway in a hilly lakeside landscape. I recognized this as being Lake Superior's head, having driven it.
