I just witnessed something that brought tears to my eyes. I was standing in line at the burrito bar when I heard people starting to clap -- and I mean a lot of people. It started as just a few, but within seconds a wave of clapping and whistling swept over the whole terminal. I had an idea what it might be but didn't want to get my hopes up lest it was just some lame professional basketball team.

I finally spotted troops walking along the upper concourse. They took almost ten minutes to deplane -- and people stood and clapped the whole time. It was really quite something.

Maybe it's true that we're near to tearing each other apart in this country over the war and other culture-clash issues, but I was so proud that my fellow travelers could set that aside for a few minutes to honor those who offer their lives to protect our right to argue.
