We have already signed up for a trip to Antarctica, not with the family. The timing wasn't right [considering the children's school schedules]. ... But you know, the trip of our lifetime was when we celebrated our 50th wedding anniversary, which is Aug. 11, 2012. We decided to take the National Geographic Trip Around the World. It is one of the best decisions as a couple that we have made. It was 31/2 weeks, 13 countries, five continents. I've never taken a 31/2-week vacation, but I said, "You know, we're only going to do our 50th wedding anniversary once, so let's really take time to smell the roses and do something that's a once-in-a-lifetime."
