We left Danang and headed north for a driving tour of the DMZ. We drove up through Hue and Quang Tri. We visited the Marine outposts the "Rockpile"and the "Razorback". We also visited the combat base at Khe Sanh. The Seige of Khe San was one of the toughest Marine battles of the war. We then returned to Hue on the new Ho Chi Minh Trail. Eleven hours, what a long day.
