Marine Staff Sergeant Tim Chambers pays tribute to Veterans on Memorial Day weekend during Rolling Thunder. Over a million Veterans on motorcycles from across the USA parade in Washington D.C. the Sunday before Memorial Day. They are met by a solitary, saluting Marine who greets them out on Constitution Avenue. The Marine stands at salute for over 4 hours, while the parade of roaring bikes drive by. SSgt Chambers has been performing his Rolling Thunder Salute for over 17 years now. Semper Fi Marine!
