Some of the most irresistible attractions of Oakland have nothing to do with the current hipster incursion. This Sunday, for example, the 35-piece Oakland Municipal Band plays at the Bandstand on Lake Merritt from 1-3 as part of its 105th season. Bring a blanket and a picnic lunch for a rousing, old school afternoon. You’ll find it on the northern shores near Children’s Fairyland. Check their website for the day’s program. Free. The Lake is home to gondola rides, a wild bird preserve (so dog walking is not allowed) and on July 24, the US Rowing Western Regional Championships. Mark your calendars.
