I believe Michigan has more lighthouses than any other state for a reason. (124)

Me and the wife wandered around the Splitrock lighthouse north of Duluth last month. The Minnesota Historical Society has done a great job preserving the lighthouse, grounds and even the mechanism that turns the lamp. The North Shore and Isle Royale are some of my favorite places on the planet.
