The film footage here includes La Paz Plaza, schools, parks, rolling hills, grazing sheep, Mission Viejo's first church (Lutheran), the then-new Orange County Airport terminal, UCI, Fashion Island, Newport Harbor, and aerial views of the contruction of Dana Point Harbor. For further memories of childhoold there's a shot of the contruction of Old MacDonald's Farm and an Indian Guides pinewood derby. Interior views of "Spanish Modern" (or perhaps Man of La Mancha Modern?) tract homes will also take you back.
Observant viewers will notice both Richard O'Neill and Tony Moiso of the Rancho Mission Viejo in planning meeting scenes. And just to make sure you know it's the late 1960s, it's backed with easy listening version of Beatles hits. My thanks to Hedy Henderson for pointing out this great footage!
