Might be more Columbus talent being regionally syndicated. Though it didn't seem to work the best with the Buckeye Country network, where the idea was to voicetrack all of the stations from WCOL.
Not all of the Buckeye Country themed stations where voicetracked from WCOL. I know WMRN-FM in Marion at the time had a WCOL jock or two and at the time had Danny Wright from WGAR in Cleveland.
The whole Buckeye Country thing was more of a Jacor thing than Clear Channel, WCOL was the first to 'drop' the slogan.
Looks like WMRN-FM and WCHO-FM are the only two left using the slogan... 102 in NW Ohio went back to 'T-102" WCKY dropped the slogan so did WGAR.
