Is this worth riding or is it mostly high traffic urban highway- 37 to 61 up to Thunder Bay? A friend and I may be riding out to GR, MN from Portland-ish and I'm considering riding to Thunder Bay and back approximately in a day from there. Is it worth doing this or is it rather boring. A loop around Lake Superior has been on my bucket list since discovering this thread: https://advrider.com/f/threads/adventure-in-the-midwest-ride-lake-superior.1342976/ and it might give me a taste for the big loop? I just noticed that it looks like most of 61 is several blocks (if not farther) from the lake anyway and I mostly wouldn't see it while riding?? Is Duluth worth visiting?
