Years ago I did a run around lake Superior, and loved it. We were in no hurry and tried to see as much stuff as we could. I would recommend the lake tour, but do the 100 hour one. This way you can see some of the wonderful back roads in Northwest Wisconsin and in Eastern Minnesota. The Mississippi River valley is beautiful in spring. The Wisconsin Indian Head area has many lovely back roads that are a shame to buzz past on the Interstate. Minnesota State Hwy 61 is another beautiful road to enjoy at a leisurely pace. Make sure you stop and look at the break waters in Grand Marais MN, simply breath taking in the morning! Sven & Ole's Pizza is a must stop too.
