Carolyn, Chris has always been torn as he travels between his growing-up home and his adult life home whether it was Minnesota, Chapel Hill or Baltimore.  Beth seemed to fly back and forth between Moscow and Louisville as if it was as simple as crossing over to Indiana.  I think some people feel the pull in both directions during the trips between "home" and "home" more than others.  With your very long trip and the accompanying weariness it just makes the longings stronger.  I'm so sorry I missed you this trip home, but your blog helped me feel like I was experiencing Walla Walla right along with all of you.  Thanks.  And safe travels from me as well as your mom.
