Duluth (St. Louis County), Minnesota

Here's another one from Melissa, my couchsurfing friend. My friend and I couchsurfed with her in Duluth in the middle of winter during a cold snap, and it was COLD. We had an argument about what was the largest county east of the Mississippi River. I said it was obviously Aroostook County in Maine. Looks like she had the last word on this one.
