Part 1: Best-selling author Tom Clavin talks about his most recent book, "Throne of Grace: A Mountain Man, an Epic Adventure, and the Bloody Conquest of the American West." It's a look back at the days of the beaver trade in North America in the early 19th century- and the epic exploration of Jedediah Smith, who managed to reach the West Coast and explored both sides of the Rocky Mountains - and yet is a largely forgotten figure. Part 2: In a rare visit to the Morning Show, WGTD General Manager David Cole talks through the format / schedule changes that go into effect today for WGTD as well as for all of Wisconsin Public Radio.
