Saigon is such an evocative name that can conjures up a thousand images in one&rsquo;s mind. As I approach on the bus from Chau Doc, weaving my way through the Mekong Delta, I can&rsquo;t help but imagine that great film Apocalypse Now. The early scenes in Saigon with Captain Willard (Martin Sheen) half drunk in his GI hotel room, single roof fan beating the humid air and waiting for his orders to eliminate Colonel Kurtz (Marlon Brando) up the Nung River in Cambodia.
