My sister was obsessed with seeing Lake Superior for some reason, so after a visit to South Dakota a few years back for a family reunion, I went with her and the kids to Duluth. The first day or two were fine, but then a weather system moved through making it chilly. It was at the height of summer, so it was a bit disappointing. But I was impressed by the forests, waterfalls, parks and lighthouses in the area outside the city. The city itself is rather dull.
