(Duluth, MN) -- A retired Duluth couple is now in their 97th day of walking around Lake Superior. Mike Link and Kate Crowley are researching the lake and have traveled more than 900-miles so far. Back when the two started in late April, Link said it was once-in-a-lifetime journey. Link and Crowley passed through the village of Wawa, Ontario to start the week. They hope to be back in Duluth before the end of September.
