The view from inside the Second Ave. Subway

I found myself standing where few civilians have been. I am approximately 55 feet underneath Second Ave. between 91st and 92nd Streets, and I am standing inside a wet, dark, round tunnel. An industrial-sized air vent hangs above me while a set of rudimentary train tracks stretch southward as far as the eye can see. In five and a half years, the Q train, bound for Brooklyn via Second Ave. and Broadway, will rumble past that spot, but right now, it is the largest construction site in New York City.
