To celebrate Father's Day, we talk with two poets whose writing is strongly influenced by their relationships with their fathers. First we have Marjorie Maddox, whose book of poems Transplant, Transport, Transubstantiation focuses on her father's unsuccessful heart transplant. Todd Davis's newest book of poetry, just out this month from Michigan State University Press, is In the Kingdom of the Ditch. Davis's poems have been featured on Garrison Keillor's "The Writer's Almanac."
