This pic is from Vung Tau, the coastal town south of Saigon.  In the background is a hydrofoil boat that is used to shuttle people from Saigon to the coast.  They get up to maybe 70 miles an hour (seems like anyway) and lift up out of the water.  They are a pretty rough ride and the machines are old (the Vietnamese seem to be able to make anything run), but one runs about every half hour both ways up and back most of the day until evening.  The trip takes an hour or so.  I think it is about seventy miles down the river to Vung Tau from Saigon.  Photo by Heide Keith
