BTW, when I was a kid, my brother and I used to take a streetcar from the Laguna Honda Station in San Francisco down to the Key System terminal at the base of the Bay Bridge, then catch the F train that crossed the bridge (on the lower deck) and went all the way through Berkeley on Shattuck, then through the tunnel to Solano Avenue, where we'd get off and walk a block or so to our cousins' house on Marin Avenue. My aunt Dorothy was married to ex Berkeley All-American Berkeley High School football player Chili Bertoli, and we spent many weekends with the Bertolis. 10-12 years old, traveling all that distance on 1940s rapid transit, no chaperones. (The rail lines were torn out in 1958, and the lower deck converted to pavement for cars.) Ah me, I do digress.
