Last night, after channel surfing, I caught two interesting PBS programs. The first was part of a series on Great Estates of Scotland and it covered Inveraray Castle, home of the Duke of Argyll who is the head of the Scorttish clan Campbell. The current Duke and his wife, part of the Cadbury Chocolate clan, are a young, middle-aged couple with three children who treat the huge estate whose attitude is a huge anti-snobery "It's a business," keeping two floors of the castle to themselves and the rest as a tourist attaction which gets thousands of tourists to the town and castle regularly, many of them Campbells from all over the world coming to their homestead. I thought the Duke and Duchess were quite down to earth and charming.
