We took 35 north to the hwy 23 exit around Banning State aprk. Hwy 23 is hilly, with plenty of twisties. The real fun however kicks in around Fondulac, at the MN WI border. Then hop on Oldenberg Pkway, aka hwy 210 west. That is where shit hits the fan. The roads are the best I've ever experienced in MN. I've been in the car scene for several years and have traveled many miles with this car club, taking me through many different awesome roads. This stretch however is the best I've ever taken.
The scenery here is comparible to out west. Big river, lots of hills and twists along the way.
Its a bit of a drive, but more then worth it.
