Ah - Wikipedia has an entry for The Bay Lights, for those who need words:The Bay Lights is a site-specific monumental light sculpture and art installation on the San Francisco Bay Bridge designed to commemorate the 75th anniversary of its opening. The installation by light artist Leo Villareal will include 25,000 individual white LEDs along 1.8 miles (2.9 km) of the cables on the north side of the suspension span of the bridge between Yerba Buena Island and San Francisco. The installation will be controlled via a computer and will display changing patterns that are not meant to repeat. The opening ceremony was held on March 5, 2013.

I have seen this on the news. That's right; it's a public art piece. In Russia, the strobing light-array would be aimed at the drivers on the bridge, and all vehicles crossing the span would be required to have "dash-cams" installed, to record theirs & others (mis)adventures in traffic.

(Dash-cams captured about 2 dozen different views of the action, when the asteroid streaked in & exploded over their rather small city.)

San Fransisco is more-redeemable city-wise than most. I lived there for several years, stationed at various navy bases. The weather gives it a rare familiarity, since I am from the hardcore maritime temperate rainforest, further north. (Forks, actually. Vampires & werewolves are the least of it.)

I learned to body-surf at Stinson Beach ... finally getting good enough to be pile-driven to the bottom & tumbled in the wash-cycle for it seemed 100 yards. The beach kept my Timex, but I was allow to retrieve my swimming trunks from around my ankles.
