After Thanksgiving in 2004, my mother and grandmother went with me on my first outing to Biltmore Estate in Asheville. This 250-room French Chateau (the largest private residence in America) is a sight to behold especially during Christmas when it is decorated for the holidays. I have never visited during the springs when the flowers, especially the tulips, are in bloom, but I hear it is a gorgeous time to visit.    What's in a name? Bilt is a Dutch town and more = open, roll
