Rock Harbor, Michigan is an imaginary town set along Lake Superior’s shore in Michigan’s Upper Peninsula. Settled predominantly by people of Finnish descent, it still retains a bit of Scandinavian flavor from the customs of the Finns. A small, quaint village built in the 1850s when copper was king, Rock Harbor is surrounded on three sides by the massive Ottawa National Forest, comprising nearly one million acres of North Woods. Anyone living below the Mackinac Bridge, otherwise known as Troll Turnpike, is called a troll. The ongoing joke in the U.P. is that trolls were easy to spot because they locked their houses when they left and locked their doors when they went to Escanaba.
