AT&T sold most of them off in the early 2000s. American Tower owns a lot of them. Some others went to individual private owners. There's a company in western MT that owns about five of the mountain top sites for instance. Very few of the rural/suburban sites are still owned by AT&T. The sites where AT&T still happens to be the ILEC in an area may have horns on a central office roof just because they're very expensive and a huge hassle to decommission.
