Emerging from a Metro crowded with families, cloudless, sunny skies and the outermost walls of the Pentagon greeted participants in yesterday’s America Supports You Freedom Walk, an event sponsored and organized by the Department of Defense to memorialize the 184 individuals who died at the Pentagon on September 11, 2001 and to honor the service of the country’s armed services. Various signs reminded walkers that pre-registration was a must and signs and banners were prohibited, while free t-shirts, commemorative dog tags, and post cards bearing an image of firefighters hanging a flag from the Pentagon on 9/11 were handed out by the event’s volunteers. Security was ever-present, though lighter and less invasive than expected. Music played in the background, a mix of traditional jazz standards and patriotic rock anthems.
