Dave Madden has never gone hunting. He's never mounted an elk hide on a plaster cast of a trophy bull. And yet, he's fascinated by taxidermy. His fascination began with his love of museum habitat dioramas, those fake frozen scenes of "nature," and it grew into a new book about taxidermy that explores the obscure subculture, as well as human relationships with animals, hunting, death and, in a sense, the after-life. Madden joins Doug on Wednesday to talk about his book, The Authentic Animal.
