The theme of the decade is community, so come celebrate with yours! The annual South Park Summer Day and Night Festival is back for a third year, helping light up a tucked-away neighborhood and showcase an overlooked part of town. The festival will feature music from Sangre Azteca, Estreno Misucal and Half After; dancing, sports, games, a health fair, a raffle and a screening of the film Rango. It’s time for fun and the ever-present game of basketball on Saturday, Aug. 13, at Martin Luther King Jr. Park. 1336 Temple Ave., Santa Rosa. Free. 2–11:30pm. 707.544.6911.
