1964-1968 Wow almost 50 years. Viet Nam 66-67. been back 5 times now. You'd never know there was a war there. Great people with great pride in there country. over 1,000,000 motor bikes in Hanoi alone and not one puff of black smoke coming from any thing. trucks, buses, bikes. Beautiful well kept parks. good place to visit to get out of the PI a while.
