In the late 1990s, when poet Ted Kooser was recovering from cancer surgery, he started sending postcards to his friend Jim Harrison, a novelist known for Legends of the Fall and numerous other books. On each postcard, he wrote a poem. Harrison did the same in return. In 2001, Kooser turned his half of the exchange into Winter Morning Walks: 100 Postcards to Jim Harrison, a collection of engaging, witty, clever, insightful poems that serve simultaneously as snapshots of a friendship and a view into a poet's daily observations.
