The Biltmore Estate in Ashville, North Carolina, is the largest private home in the United States. It was built by George Vanderbilt, the grandson of the wealthiest man in the world. We tour the estate with Burt and see how they prepare for Biltmore's Christmas celebration. From Santa Claus and Eggnog to Wreaths and Poinsettias, Burt explains what became part of our Christmas tradition and why.
