Glacier National Park has a fleet of 33 “Red Buses” manufactured in 1936 by the White Motor Company. They were all refurbished in 2002. When I wasn’t at the wheel (Ha!), our driver/guide (or “Jammer”, short for “gear jammer” as they are referred to up there) kept us informed and entertained during our 4 hour tour from the west entrance to Logan Pass and back. Note how the canvas top was rolled back to enable people to pop up and take photos when the bus was stopped.
