Ever wonder about the meaning of that surreal mural near the corner of Figueroa and Avenue 61 in Highland Park — the one with the Aztec calendar stone, Quetzalcoatl's acid-green plumage and an infant in a blue orb? Isabel Rojas-Williams, executive director of the Mural Conservancy of Los Angeles, would be happy to tell you. One Saturday morning every other month, she and other MCLA volunteers lead public mural tours in neighborhoods across L.A., from downtown's Arts District to Venice. Each 90-minute walking tour gives locals the lowdown on significant pieces of street art and the muralists who painted them. Don't be surprised if well-known artists, like RISK or Willie Herrón III, make a cameo to talk about their latest piece. A $20 donation gets you access to one year's worth of MCLA tours. There's no better way to learn about these vast homages to history, politics and the cultural flavors of this city's ethnic stew. Location varies. 155 W. Washington Blvd., Ste. G1, dwntwn. (213) 291-6900, muralconservancy.org. —Rachel Heller
