More than infrastructure, a city is more deeply coloured by its content. The people here. The activities. The way they drive. The way they earn money. The way they greet each other. This is a city of the present that keeps lingering in the past tense.
Don’t work too much to picture, because you’ll find yourself drying up. Work off-picture, and then put it onto it. Work as much as you can from impressions. And be selfish about your own experiments that you want to do.
