I've left the 'puter for awhile to look more closely at the screen and take in the marvelous marchers. Is it me or does our President seem a little solemn? Perhaps he's tired but every now and again the camera catches him in a pensive mood (except, of course, when his home state marched passed) and I don't see him commenting much to Laura or anyone for that matter.
I've noticed his mood too. Could be he's worried Clintoon will show up again to take over the day like he did 4 years ago.
I would imagine that they are all tired--after all it has been a long day, and they still have the parties to go to tonight. And after sitting for a while, it probably just hit them at how looong the day has been!
