Southern MN - it goes through Faribault and Mankato.
Actually it starts in Wabasha from there to Zumbro Falls it’s good. The Wabasha to co. rd 2 was just redone a couple years ago. from there to Zumbro Falls it good to, but I can’t remember if they actually redid it then or not. It is a two lane road from Wabasha to Faribault. Nice twisty road for Motorcycles from the Wabasha to Zumbro falls ride. The ride from hwy 52 (Zumbrota) to Faribault is like a cow path, and very well traveled. (very bumpy) Can’t say how it is west from there tho since I don’t go that far.
