Route from S. Dakota to Devils Tower in Wyoming

I drove it in a car August 2017. Very good road, a couple of up and down grades that will make you sit up and pay attention to what you are doing, but nothing at all radical. Basically it will be a very enjoyable ride.

Also stop at the Wyoming welcome station just down the hill from the Vore Buffalo Jump, it has some very nice displays, not just a room full of brochures, so some neat stuff to look at.
