Today the Patriot Guard Riders were honored to be invited by the family of U.S. Marine Corps veteran, Marvin Thibodeaux, Jr. to stand "tall and silent" at his inurnment service held at DFW National Cemetery.  Just prior to the mission briefing, the family and all riders gathered at the visitor's center where the Certificate of Appreciation was presented to Mr. Thibodeaux's daughter, Shannon.  At the shelter, she was presented the American flag.  When the service concluded the riders returned the flags to the support vehicle, furled and stowed them, were debriefed and dismissed.
