At the end of May, a Minneapolis kayaker will embark on a journey from the source of the Mississippi River at Lake Itasca to the Gulf of Mexico. Devin Brown would be the first Black woman to solo the length of the river. She’ll be talking about the journey in a panel discussion on Thursday alongside Eddy Harris, an author and adventurer who has paddled the entire river twice. He wrote a memoir called “Mississippi Solo” reflecting on his first trip in the mid-1980s. Brown and Harris joined MPR News host Cathy Wurzer to talk about the upcoming journey from source to sea.
