Bay seniors understandably avoid tours of their own city but this Sunday May 2 you will want to check out the Cinco de Mayo dance tours, baile en la calle, based around the historic murals on 24th Street and Florida. Local choreographers will be performing at 11, noon, 1 and 2 pm. It’s a noble effort to preserve the character of the neighborhood against the tech onslaught. If your appetite for wall works is further aroused, definitely check out the 4-hour city Street Art tour the following Saturday on foot and by van presented by the 1AM Gallery. $49.
