On the morning of their 1960 field trip to the San Francisco Zoo, Frederic Burk School children, accompanied by their teachers and the bus driver, board a classic Greyhound bus. The sleek silver coach, decorated with the company’s iconic running greyhound logo, waits at the curb as the group prepares for the journey ahead. Once a common sight across America, Greyhound buses were a familiar part of mid-century travel for both long-distance trips and local charters. This moment captures the excitement of departure, marking the start of a memorable day away from the classroom.
