Night never really sets in thoroughly in Chicago. We get closest to dark in summer, when the trees’ shadows leaf into a canopy, blocking out some of the streetlights’ glare. The lights are overly bright, to the point of making it hard to sleep.
How would we be affected were the city naturally dark at night? If the streetlights were fewer or more puny? For stay-at-home types, it would be quieter, more soothing; for live wires, much more an adventure to be out on the town.
