There’s plenty to do this weekend in Stockbridge. The fountain across from Stockbridge City Hall is going pink for “National Breast Cancer Awareness” month. It will turn pink at 6 p.m. on Friday. The water-soluble pink dye is safe for the environment. Friday also is the kickoff for the Third Annual Bridgefest, which features arts, crafts, food, entertainment, an interactive children’s area and a free community concert. The 7 p.m. to 9 p.m. concert features a Tribute to Motown by the band Unisoghn. Bridgefest continues Saturday with a half marathon and other activities. There also will be a free community health fair from 9 a.m. to 1 p.m. in the ballroom of the Merle Manders Conference Center, 111 Davis Rd in Stockbrige.
