I may not be remembering correctly, but as a kid growing up in the Excelsior District,I remember the following things
you don't see anymore:
1. A local SF TV show with a character called "Carl the Carrot".
2. Jitney's- although I now live in Ohio, my SF relatives
tell me Jitney's are now gone. When I was young, my mother
an I would take Jitney's from the Excelsior to downtown SF
to shop (down mission St.).
3. "Its It" ice cream at Playland at the beach.
