What are you doing Saturday? Because you need to do this instead. On Sept. 23, the Smithsonian holds its annual free museum day, with the chance to visit scads of places for free. (This is in addition to last week’s free museums). You need to sign up and download a free ticket good for two people in advance. My favorites on this list would be the Japanese National Museum downtown in Little Tokyo and the Autry Museum of the American West off the Santa Ana Freeway near Dodger Stadium. But there are also many other museums on the list, including the San Diego Air & Space Museum, the Laguna Art Museum and the Howe Waffle House in Santa Ana. Be there before the museum opens, it’s going to be crazy busy. Learn more: smithsonianmag.com/museumday/museum-day-live-2017/
