Late last month while my wife, Carol, and I were staying in Asheville, N.C., we decided to visit the Biltmore Estate. Only a couple of miles southwest of town stood what could only be called a castle. The building is the largest privately owned house in the United States and dwarfs the building featured in the television show, Downton Abbey. Built over six years from 1889 till 1895, 8,000 acres of green rolling hills surround the magnificent three-tiered structure. The French Broad River, which I rafted a number of years ago, splits the property.
