My husband, 6 year old daughter, and I will be in Minneapolis later this week and over the Veteran's Day weekend. My husband has a conference, but we are staying a few extra nights to explore the area. We would like to take a day trip from Minneapolis to the Duluth area. Since we will only have the one day to visit (including round-trip travel time), what are your suggestions for activities, must-see sights, and restaurants in order to maximize our short amount of time? Thanks in advance!
