Saigon, well, Saigon doesn't really have a "soul" though that gives the wrong connotation. There is no misdirection or obfuscation about what this city is. I did not come here with that knowledge. I spent a significant amount of time looking for the soul of Saigon. Wondering when, just as in all Western cities, I would come around the corner and see What's Really Going On.
But... you don't need to look hard enough. It's all right here on the surface.
... surface might in fact not be a strong enough word. Surface implies that there is a deeper level, and there isn't. This city is two-dimensional. There is no insertion into the Hollow World through the poles. There is no symbolic topographical mapping.
What you see is damned well what you get.
Saigon is hot, until recently, there wasn't much AC. There still isn't. And so people live outdoors, where at least the heat can rise away.
Most restaurants here are outside. On street corners. Pots of pho. And com (pronounced almost like cum, but with a blowing out of the cheeks like when you were a kid and held your breath). And tiny chairs. And beer. Cheap beer, 15 cents for some local brewed rough stuff that tastes like fresh chicken and rusty springs. And card games.
People will sit on their motorbikes (everyone has a motorbike), and talk with their friends, in the middle of a park. Or go down to the riverside and sit on their bikes with their girlfriends. And get ice cream. Or some other small snack.
All day, the city is covered in lines of motorbikes. Huge sidewalk parking lots. People sit outside of restaurants on their motorbikes and drink coffee, or eat.
People drive down the street next to their friends, and talk, while on their motorbikes. I've seen two motorbikes, each with half of a family driving down the street next to each other. As if a minivan has been molecularly rearranged and no one had noticed.
There are very few traffic rules, excepting the wearing of safety helmets for everyone over 6 years of age. People will drive the wrong way down roads, through red lights. Cut people off and fill the streets. It only works because there are very few cars.
Imagine Miami, but if everyone drove a motorbike. All that extra pavement and sidewalk would be covered, and used. All the time.
And... that's it. That's, in large part, everything. We haven't talked about the people or the culture yet. But the first thing you have to accept in order for the rest to make sense is how simple it is here.
There's food, friends, alcohol, sex, the beach, sports, dance.
That's it.
