I've been wondering this for awhile...When is Mainline going to change Fly's call letters, or are they? It doesn't make sense to keep Z-93's old WGTZ calls, since it is directly tied to the lineage of that station(We're Great Trails Z-93 was what it meant). I know that it takes awhile to change calls, but it has been two months plus now. I know that WFLY isn't an option, since Albany, NY's CHR Fly 92.3 already uses those calls. Maybe WWFL, WDFL(We're Dayton's FLy), or my personal favorite, WING-FM. 8)
