One of Los Angeles’s great landmarks is the Griffith Observatory, an architectural gem that mixes art-deco and Mayan aesthetics. It’s perched on a ridge in Hollywood Hills above Los Felix and provides a stunning, wide view the L.A. basin. It naturally is a major tourist draw, with thousands upon thousands of people winding their way up the hills and canyons each day to visit this icon of La La Land. It’s a functioning observatory and as such there are working scientists, astronomers, educators, and space enthusiasts, et. al. — nerds! — congregated and fussing about amid the tourist hordes snapping selfies along the viewing terraces.
