At the end of every Nosy Neighbor post is a long list of links to previous entries in the series. Occasionally, I deadhead the list, removing the questions that no longer seem relevant. Even so, I bet many folks have never really looked at the list, and this roundup of eight all-time greatest hits will answer questions you have about the neighborhood.

And your questions are welcome! Even stupid ones! (Whoever said no such thing exists was a liar.) Email tribecacitizen@gmail.com or text 917-209-6473.

How come every every film and TV shoot seems to have a trailer with doors marked “Lucy” and “Desi”? —E.
At first, I figured they were code names for actors or characters so that civilians wouldn’t loiter outside hoping for a glimpse of Mariska Hargitay. But then a bell went off….

At 289 Church, opposite the Tribeca Grand Roxy Hotel, there’s a building with flashing colored lights in the windows. I have no idea why and I can’t see what/who belongs in the building. Any clues? —Greg
The short answer: It’s art. The long answer: That’s the studio of Steven Rand, the artist who owns the building. There’s actually a sign in the ground-floor window directing the curious to churchlights.net, which in turn sends folks to stevenrand.info. More….

Let me ask for your assistance in solving a minor mystery which has plagued me since I started reading Tom Shales’s “uncensored” history of “Saturday Night Live.” The book mentions the Blues Bar, a “seedy joint” rented (or bought) by Dan Aykroyd and John Belushi just after the show started in 1975 to hold post-post-show parties. I’d love to know where the bar was located (and what’s there now) but the most precise location information I can come up with is that it was “somewhere near Canal St.” Any ideas as to where the original Blues Bar might have been? —Paul C.
The short answer: 282 Hudson (at Dominick), where Cody’s Bar & Grill was located. The long answer….

After walking by 47 Vestry countless times, I realized I had no idea what the foreign characters painted on the façade mean. So I asked myself to look into it.
The answer was not as simple as you might expect.

I’ve walked past this structure for years and still have no idea what it is. Any insight? —R.
It’s Con Edison’s Leonard Street Substation. What’s a substation, you ask?

What’s the story behind that cute row of houses on Harrison Street, west of Greenwich? I always wonder as I walk to work. —A.
They were moved there from Washington Street.

Why does the building on Duane (just east of Hudson) say “Whalebone”? —A.
The building says “Whalebone” because 161 Duane used to house George Messman, the last whalebone cutter in the U.S.A. More on what has occupied the building—and what whalebone was used for.

I was wondering if you could do a Nosy Neighbor post on the bins that Downtown Express, Manhattan Family, Learning Annex, Big Apple Parent, and so on place all over. They seem to become eyesores—covered with graffiti, trash, broken plastic doors, stickers, etc. Do they need permission from the city to plop them down wherever? And do building owners have a right to ask them to be removed? —Miriam
They’re a blight! Especially the ones that block intersections. They don’t need permits, but they can’t legitimately expect not to be abused. So feel free to throw one in a dumpster.
