My wife and I (66 and 69) are planning a trip to Minnesota and North Dakota for next summer. 2 of the remaining 5 stats we have not visited. Will likely spend 4-5 days in each state starting with a flight to Minneapolis. We will mostly be driving for some general site seeing with some hiking/biking as available. Would be interested in getting feed back on sites to visit and best route through Minnesota to get an overview of the state. We will likely fly home from somewhere in North Dakota. Thanks in advance for feedback.
