A page from Rally's ride
In the book, Rally's favorite moment is the window: the train starts, the ocean slides by, and a white bird keeps pace with the car. A dog who rides MARC Train gets a version of that, as long as the rules above are met. The free coloring and activity pack has a coloring page of that window, if your kids want to draw their own dog in the seat.
