Deer snarl traffic on Golden Gate Bridge

Here's a traffic jam you don't see every day.

Two deer ran across San Francisco's Golden Gate Bridge on Friday, snarling traffic during the evening rush hour. Traffic slowed behind the prancing pair as they made their way from the Presidio to Marin County, delighting rubberneckers, who posted photos and videos of the spectacle to social media.

The deer were reported to the California Highway Patrol, but the unusual commuters were already gone by the time police arrived, officials said.

According to the San Francisco Chronicle, the CHP received a report that one of the deer may have been struck by a car, but the photos and video suggest that the deer were unharmed.
