Walking along the evergreen streets in Saigon

Saigon used to be a beautifully green city, maybe still green but the image of a charming city has gone. Back in 70s, I was just a little kid, but still remember the image of Saigon in the old days.
Not much traffic, much cleaner, less populated, less polluted and it seemed people at that time behaved more properly.
