It had been a tradition in Santa Rosa since the ’70s, but then the Day Under the Oaks open house at Santa Rosa Junior College went on hiatus. It returned last year after four years off. To say that it was missed is an understatement. Now the campus opens again this weekend with family fun and educational activities for all. Every department offers exhibits and demonstrations, and long-standing activities like the Native American dancers and planetarium shows are perfect for introducing the event to a new generation of curious kids and adults alike. A Day Under the Oaks happens on May 4 at the Santa Rosa Junior College campus, 1501 Mendocino Ave., Santa Rosa. 10am to 4pm. Free. 1.800.564.SRJC.
