Spilling Thought: A brilliant, fog-free #sunrise graces the #GoldenGateBridge in this photo taken from Golden Gate National Recreation Area (@goldengatenationalparks) in the Marin Headlands of #California. On this day in 1937 -- 79 years ago -- this iconic bridge first opened. With towers extending 700 feet into the sky and over 100 feet beneath the #SanFrancisco Bay, the bridge is an engineering marvel. In addition to driving, you can walk or bike the entire length of its 1.2-mile expanse, bounded on either side by spectacular scenery.
