They take O’Keefe’s Isuzu Metrovan down to the southeast tip of the Bronx, beneath the Cross Bronx Expressway, nearly as far as Locust Point. O’Keefe’s SecLink points them down streets lined with ancient brownstones and then through blocks of commercial-zoned properties, many large brick and concrete structures. At length, they come to a warehouse bearing the sign: Edgewater Shipping. The place is dark, no lights showing inside or out. O’Keefe drives past and parks just up the block at curbside. A passing semi sounds its airhorns.
