If Hall County officials thought additional public input meetings would generate greater turnout and broader interest in a new round of special purpose local option sales tax, they got a rude awakening Thursday night. A vote on the 1 percent sales tax, which would fund capital projects throughout the county, was postponed this fall after turnout lagged at three public input meetings in June. Local officials had hoped that added meetings Thursday night and on Dec. 11 would bring some clarity to voters and, perhaps, drum up support for passage of the tax.
