I was a phone company cable splicer for a while, so I tend to notice utility lines. On top and below left, a mainly cable TV cluster on Berry near N 8th in Williamsburg.
Above right, a waterfall of wire serves Bryant Park -- for stuff like the huge Citibank ice rink / mall last winter -- from a power generator on Sixth Ave.
Above left, a grainy closeup of a naked phone company splice -- where trunk cables, which can have thousands of wires, are connected. Splices being worked on usually have a rubber "boot," like the one above right, to protect them from the elements until they get an aluminum case.
And finally -- near the splicing above, in front of Greenpoint's Newtown Creek Wastewater Treatment Plant on Provost near Green -- an old fire alarm box. I fear its old wires, above left, may be connected to the wrong utility line -- note the ghostly glove of the last person to pull the alarm, above right.
