If Bobby Troup had followed US 2 along the Great Northern instead of Route 66 beside the Santa Fe, he might have written an entirely different tune: You go through Minot, Essex and Sandpoint but don't forget Skykomish... Well, perhaps he chose the better route for lyrics after all. Still the Hi Line has its appeal and in this scene the 4410 West is slowing for a crew change in Shelby, MT on a late September afternoon.
