History of the Chain of Rocks Bridge & St. Louis Leviathan

Sue Thomas first talks to St. Louis Historian Jackie Dana about the history of the Chain of Rocks Bridge and the little buildings that look like castles that you can see from the original bridge. What are they? Then, Public Historian for the Missouri History Museum, Andrew Wanko stops by with two great stories from St. Louis history...the St. Louis Leviathan and the St. Louis Tinfoil. The tinfoil is the oldest sound recording that we can still hear today!
