Progress and change may mark this South Hall city’s agenda, but officials are working to preserve a piece of history that traces back to its roots. Oakwood is looking at making some improvements to the 4.14-acre City Cemetery, which is off Plainview Road and across from Oak Street. “The main thing we’re doing right now is trying to keep the grass maintained, trim the weeds, things like that,” City Manager Stan Brown said during a visit to the cemetery Monday morning.
