in San Francisco is a perfect way to spend an overcast Saturday in San Francisco. Located on pier 15, the Exploratorium will keep you busy for hours. I loved the fog bridge outside designed by Fujiko Nakaya. Water pumped at high pressure through more than 800 nozzles creates an immersive, foggy experience - which is funny considering San Francisco is often hidden in the fog.
