We drove from Yellowstone’s East Entrance across the Chief Joseph Scenic Byway and Beartooth Highway through Cody and all the way over to Mammoth Hot Springs.  It’s definitely a summer trip – that entrance is only open May to October.  The Beartooth Highway rises to 10,947 ft. and has warnings about wind and cold.  Luckily, we had no freaky winter storms.  We did have tons of wildfire smoke.
