AT&T still has quite a bit of large lead cable in the air along N. Tryon Street in Charlotte. It's apparently working because many of the splices have been upgraded to pressurized '2 type' splice closures (waffle closures). In my last trip, I saw that a 100 pair going to a fairly new office building was feeding from one of them. Just because it's old doesn't mean it doesn't work.
Verizon also has quite a bit of it still in the air in Hampton, VA and Alexandria, VA.
