I travelled this highway in 1997 with our friend Eugene...and it was such a spectacular route I looked forward to driving it again someday. We spent the first half of one day driving from Red Lodge to Cooke city before heading into Yellowstone Park. Most of the route we drove about 35-40 miles an hour partly because the Sturgis Motorcycle Festival was also doing a tour of the same highways we were driving. I want to go back again and stay for a couple days in Red Lodge and in Cooke City. A truly stunning part of the world, and the towns are really cute and hospitable.
