George was really in his element today. I volunteered as a photographer for the USA Science & Engineering Festival, a massive science fair that basically took over all of downtown Washington this weekend. I cannot think of a single field that was not represented. I’m talking huge – this festival not only took up three blocks’ worth of the National Mall, but spilled with impressive size into Freedom and Wilson Plazas and over a sizable stretch of Pennsylvania. It was a sight to be seen.
