Poetry isn't Mattie's only creative hobby. He's also an avid rock collector, with rocks from all over the world including ones from Ireland, a German castle and a piece of the Berlin Wall. His latest addition to the collection is a rock he picked up just the other day in Chicago!
Oprah has a few more new rocks for Mattie to add to his collection: rocks inscribed with the words "Peace," "Wish," "Mattie," "Oprah" and "Heartsongs."
Sadly, Mattie died on June 22, 2004, but his positive impact on the world lives on.
