Question: In which county is the city sharing a border with the capitol of the state where WYFG is located?

Knowledge 1: WYFG
WYFG is a radio station simulcasting the Bible Broadcasting Network for the Gaffney, Spartanburg, and Greenville areas of South Carolina as well as some of the western suburbs of the Charlotte area. [SEP] Knowledge 2: Charleston, South Carolina
Although the city lost the status of state capital to Columbia in 1786, Charleston became even more prosperous in the plantation-dominated economy of the post-Revolutionary years. The invention of the cotton gin in 1793 revolutionized the processing of this crop, making short-staple cotton profitable. It was more easily grown in the upland areas, and cotton quickly became South Carolina's major export commodity. The Piedmont region was developed into cotton plantations, to which the sea islands and Lowcountry were already devoted. Slaves were also the primary labor force within the city, working as domestics, artisans, market workers, and laborers. [SEP] Knowledge 3: WWNQ
