I fear that this thread may become excruciatingly long, because the Mekong delta is one of the places on earth that made the biggest impression on me and where I took the most photos. And some of the photographs weren't even all that bad (just my opinion, pay no mind).
Living in a swamp is something I have always known about, since I grew up within spitting distance of bayou country in the Deep South of the United States. I saw plenty of people living in rickety shacks on stilts, spending most of their time on questionable boats, and I also know what a swamp night is like -- the insects, the snakes, turtles, furtive furry creatures and fish flicking their tails unexpectedly out of the water.
Most of my photos were taken in the height of the day, since that's when they take tourists into the backwaters, but I well imagine the ambience of the Mekong when night falls.
The first section that you see is still "in town" which is why it is so busy. I am pretty sure that this is near Can Tho. As you move away from the urban area, the waterways become much more bucolic.
The children everywhere in the Mekong seemed so incredibly happy -- and they loved seeing visitors even more.
Oh, I hope this thread does become really long! I've always read about the phenomenon of people living right on the water, but I don't think I full imagined it. These pictures are truly worth many thousands of words.
That is not a placid river, either! In the "town" pics, it's obvious that it's moving quite rapidly, with eddies and undercurrents and other dangers.
