Unfortunately, I'm at a point in my studies where I'm not able to spend as much time as I'd like researching this. I was able to do a little detective work and discover that the parade passed a the address 205, and featured a China, Glass and Toys seller by the name of Max Schwan, which showed up in Norfolk, Virginia. There were many such parades across the U.S. in 1916 urging the government to make appropriations in preparation for war. Unfortunately, most news accounts fixate on the horrific suitcase bombing in San Francisco, California, which makes it difficult to find more details about our parade.
You should be able to make out the sign in the photo below when you open it in X2Large size on Smugmug, but if you're in a hurry, it reads "Aeroplanes - Are the Eyes - Of the Army & Navy - Aviators & Students - Curtiss Aviation School - Newport News, Va." The sign sheds a little light on the name of the plane they are leading, the Speed Scout, which was alleged to have a top speed of 105 mph.
Next up will be some photos of airplanes at the Curtiss School. I believe I'll hone in on a flying boat, and I have more than one model, so I'll start with the model F.
