A 1,000 mile hike to protect the Great Lakes

This week on Seeking Change, Christina Shockley spoke with Loreen Niewenhuis. She's a Michigan author who hiked 1,000 miles to parts of all the Great Lakes.  She wanted to learn how this water that surrounds our state-- and defines our state-- works. She also wanted to learn about the concerning points for the lakes.  She'll write about this experience as well, in a book out early next year.
