Whats the borderline between Brooklyn and Queens?

The maps shows the line

but my mother points somewhere else.

To a nearby street

where people laughed and meet.

A noisy street, the subway ran above covering the sun.

The different foods had  people on the run.

When I was kid, I would go there when it was summer.

There was a breeze from the subway cart as it passed through above.

The sour smell of shaded sidewalk and dirty rubber boots are all part of my roots.

And in the memory, there were  shouts and laughs from people that spinned like the wheels of the subway

as it went through the fast clockwork of the city.
