Gainesville City School System board members held two of the three required public hearings Wednesday on the school system’s tentative tax rate, but the hearings did not include any comments from residents about the rate. Only two people turned out for the 1 p.m. hearing Wednesday, and only media attended the 5 p.m. hearing. “My sense is that means that people are supportive of the students in our schools,” board Chairman Brett Mercer said after the second hearing.
