This is the second in a two-part series of conversations recorded at George Washington's Mount Vernon as History As It Happens goes on location, with special guests historian Joseph Ellis and Doug Bradburn, Mount Vernon's president and chief executive.

Is it possible to talk too much about slavery at a historic plantation? How does an institution as popular and important as Mount Vernon interpret the past to hundreds of thousands of Americans who visit each year, many of whom revere George Washington as a hero? Listen to Joseph Ellis and Doug Bradburn discuss the problems with the "history wars" -- the endless conflict over who owns the past.
