Hanoi is a more sedate city than Saigon. The traffic is much lighter, and in the cooler air under tree-shaded avenues, the smog is more tolerable. Hanoi lives on a scale more comprehensible than Saigon. The trees are smaller, more abundant, and not so tall and tropical like those of Saigon. I stroll along the fine mansions, taking in their faded, colonial French glories, their expressive arches, French windows, and wrought-iron balconies. Every structure holds itself up proudly in a state of elegant decay.
