at the Manhattan Grit Chamber. (We passed by the Bronx Grit Chamber last year.)

From the NY Times:

The best places to see the celebrated products of New York — its Broadway talent, its skyscraper architecture — are well known.

But the best place to see Manhattan's byproducts — what is stuffed down its sinks, flushed down its toilets and washed from its gutters — cannot be found in tour guides. There is perhaps no better vantage point than the Manhattan Grit Chamber, which strains solids from much of the borough's sewage as it flows underground to the Wards Island Wastewater Treatment Plant. . . .

"We get a lot of turtles and fish. . . . We've had a canoe come in here; it got caught on the screen. We've had pieces of telephone poles, Christmas trees. Oh, you name it — mattresses, dead dogs. We got a live dog once."

"The second floor of this [sanitation] garage, long deemed too weak to support vehicles, has become a gallery of sorts, home to hundreds and hundreds of paintings, photographs, posters and objects, neatly framed and mounted on the walls. They are varied in every way — from style to age to material — except for one: almost every last piece of the collection was rescued from household trash by New York City’s sanitation workers as they went along their daily routes."

Part of the anti-butt brotherhood

That's what the registration sticker on the windshield says, but this looks like a much newer Gazelle replica of a '29 Mercedes.

Why?
