Question, gentlemen: The river on the right is labeled "Mekong." What is the name of the river to its left? These two both branch off at the same point north of the border.
The river running parallel to the Mekong on its south side is the Bassac. The two are connected by canals. In any case. Sa Dec, where Kerry was on Christmas Eve, December 24, 1968, is 55 miles or so from Cambodia - probably a 3 - 4 hour ride from Sa Dec. Kerry was about as close to Cambodia as would have been sitting in a bar in Saigon - also about 55 miles.
