Yeah on National Geopgraphic The 275 best drives in the U.S. So far they have been spot on. I have gone to Montanna twice to ride between Yellowstone and Glacier. Never have made it. There ar so m any diversions that I just get to wandering around until it is time to go home.
Idaho (if you are asking me): Salmon River Scenic Route, Stanley Idaho to Darby Montana; Lake Couer d'Alene: others I would have to check my blog. It would be hard to go wrong.
