Keep Cobb Beautiful staff and volunteers invite you to help enhance our community for generations to come. By planting a tree, you will clean the air and water, beautify communities, provide homes for wildlife, conserve energy and prevent soil erosion. Help beautify the grounds of North Cobb Senior Center Saturday, Feb. 24, with a tree planting from 9 a.m. to noon. The senior center is located at 900 South Main St., Acworth. Please volunteer at keepcobbbeautiful.org or call 770-528-1135.
