Today, Patriot Guard Riders stood "tall and silent" in honor of David Doss, a US Navy veteran.  The Certificate of Appreciation was presented at DFW National just prior to departure for the committal shelter.  As the procession was approaching the shelter, it was learned that the Navy Honor Guard was not present.  The PGR stepped in to fold and present the flag to Mrs. Doss.  At the conclusion of the service, riders returned the flags to storage, were debriefed and dismissed.
