My former employer...Level(3)...also saves scrap copper. The office I was based out of has 2 bins. One is used for low voltage cable and the other is for high voltage cable.

I can imagine that LECs are making frequent trips to the scrap yard due to the sheer volume of copper that they support.

When I saw Ed writing about the Macy's building, I envisioned it must be set up the same way as the one at Downtown Crossing here in Boston. The former Jordan Marsh flagship building has a store on the ground level and telecom condos on the upper ones.
