In the weeks since NBC aired a revival of The Sound of Music, the real von Trapp family and the vacation lodge it runs in Vermont are in high demand. And yes, the family was watching as Carrie Underwood took over the role of Maria von Trapp, made famous on Broadway by Mary Martin and on film by Julie Andrews. The von Trapps moved to Vermont in 1942 after visiting during a singing tour, built a rustic farmhouse in Stowe and started taking in boarders. As a ski industry developed in the area, they expanded. The 96-room chalet-style inn is the height of charm during the holidays. On Christmas Eve, guests get a special treat: The von Trapp family sings Christmas carols with the guests. But no songs from The Sound of Music.
