Frederic Burk School children line up with their teachers and bus driver before boarding the bus for their 1960 field trip to the San Francisco Zoo. The children, dressed in jackets, sweaters, and hats, smile and wait their turn to climb aboard. The bus driver, wearing a uniform and cap, stands at the door to greet them, while two teachers watch from behind. This cheerful moment captures the excitement and anticipation of a day away from the classroom, heading toward one of the most memorable outings of the school year.
