Wednesday was free SF Zoo day. Free in SF? = Jam-packed.
The gorilla enclave was particularly memorable. One ambled about with a new born clung on back. One examined fingernails under a tree. Another repeatedly struck the thinker pose.
The pictured leader of the pack impressively posed on the front rock. Really stared at people. Jutted head up (‘what’s up’ and/or ‘bring it’). Yawned.
