Today the Patriot Guard Riders were honored to be invited by the family of Calvin Nix to stand "tall and silent" at his interment service held at Grove Hill Cemetery, Dallas, TX.  After the mission briefing the riders took their position on the flag line to await family and friends.  The Certificate of Appreciation was presented to Calvin’s next of kin, Alan as was his flag.  At the conclusion of the service, the riders returned the flags to the support vehicle, furled and stowed them, were debriefed and dismissed.
