Visiting the DMZ and Vinh Moc Tunnel (Địa đạo Vĩnh Mốc)
It is still early, when we hurry up and get a bite to eat before we hustle over to see Mr. Tinh. After a short briefing we are ready to roll. Mr Tinh and his driver sit in the front, the three of us in the back seat. Today we are going on an excursion to visit the former DMZ and the Vinh Moc Tunnels.“DMZ,” which means demilitarized zone, is a military term that refers to a combat-free area between two enemies. The boundary between North Vietnam (officially the Democratic Republic of Viet Nam) and South Vietnam (officially the State and later the Republic of Vietnam) was established as the Ben Hai River. The river ran approximately east-west, approximately on the 17th parallel. The DMZ extended five kilometers on each side of the river. (http://www.u-s-history.com)
