Description:Ninety-four years ago Wednesday, a Norwegian boat captain named Gerhard Folgero steered a small sailing vessel under the Aerial Lift Bridge into the Duluth harbor, marking the end of a remarkable journey that replicated the voyage of legendary Viking explorer Leif Erikson to North America.Folgero built a 42-foot-long wooden ship — with a carved dragon's head on the bow, shields lining the sides and a square, white-and-red striped sail — recruited a crew of three men and successfully navigated the North Atlantic, dodging icebergs off the coast of Greenland, before sailing through the Great Lakes to Minnesota.
