FORSYTH COUNTY -- The usual quiet that circulates through libraries was replaced by a buzz of voices and energetic excitement Thursday evening. More than 70 patrons attended the Forsyth County Public Library’s 20th anniversary celebration, which was held at the Cumming Library Aug. 25. The event included a tour of the branch, a small ceremony with celebratory remarks and cake cutting and a bilingual story time with Llama Llama, a well-loved children’s book character.
