Driving down the highway, all seems normal. Then in off in the distance....
First a sample before driving on.

The Enchanted Highway is off Interstate 94 (Exit 72) approximately 20 miles east of Dickinson, North Dakota. It then extends for 32 miles south to the town of Regent. The seven sculptures are spread out along the 32 miles of The Enchanted Highway.
