The postcards are all mailed and we're packing up to leave this wonderful hotel room we've had since last Monday.
One of the more serious things we did on this vacation was to visit the United States Holocaust Memorial Museum. Wikipedia also has information on this museum. It's a serious place. I've known about the Holocaust almost all my life, and this museum made my throat close up on me a few times. 3 hours is the bare minimum you need to tour it. It's a crushingly busy place, too. Don't miss it if you're ever in Washington, DC.
Both places will keep perspective in your life.
