If you want some real excitement, take the road over the Big Horns in NE Wyoming US14. My 'Mountainous Driving' book calls this road the 'Oh, my God' hill! LOL It is 8 miles of 8% and then 10 miles of 10% up the west side. There is an easier route on Shell Canyon Highway US 16. Sheridan and Buffalo are on the east side.

Highway 14 continues east and loops down to I90 at Gillette and then back north to within 5 miles of Devils Tower!

And if you go thru Iowa, the Amana Colonies are near Iowa City on I80. They were settled by a group like the Menonites or Amish. It was settled in 1855 and was a complete socialist community. Individuals didn't own anything. In more modern times they had many factories making clothing and wool, furniture, food products, etc. The government forced them out of the socialist community and made them allow private ownership, eventually. Anyway, the food is excellent - served family style - bring bowls of veggies, potatoes, etc rather than individual servings.
You would never tell Wyoming is my favorite state and I would live there except for the temperature and I spent 39 years in Iowa where I grew up! Ha HA HA.
