You might drive South of the Twin Cities on highway 61 which runs close to the river once you get to Red Wing or Lake City. Lots of eagles there. In Winona there is Garvin Heights which offers a high level view of Winona, the River and Wisconsin. Stop by Winona State University and walk about; it is the most beautiful university park in Minnesota.
Cross over to Wisconsin in Winona and drive back up North on 35. Go to the overview in Alma, stop in Nelson for great home made icecream, continue North to Stockholm. There is a lot going on and it's beautiful. On sunny Sundays it sometimes looks like a sportscar rally.
If you see a yellow Ferrari Dino, that's not me.
