The first is in Brooklyn – around Prospect Park South. The second is in the Bronx – around Fordham Manor. If you go to the Cloisters and walk around towards the back, you will see a very interesting building over in the Bronx. With a green dome. Google maps said it was Fordham Manor.  An expedition for another day.

Two ZIPs – 11241 and 11243 in Brooklyn have exactly one service request each directed to the department of Housing Preservation and Development. Mildly curious. So what are the odds that I will reread this blog post and dig up the specific complaints / service requests? Not very good so I decided to see what they were right now. The one in the 11241 ZIP is “Unsanitary Condition” at 16 Court Street, a residential building. I can understand one building having only one report ever about unsanitary conditions, but a whole zip code has only one in 13 years? I mean this is New York – when has there ever been a shortage of unsanitary conditions in this city? Or people complaining about them? Weird. The other is in the 11243 ZIP code and pertains to the “Ventilation System” at One Hanson Place.
