As a child, "1607" was engraved indelibly onto my mind, since it was our family address during parochial grammar school, which was a block away, in a former San Francisco, California.
Yes I remember that from learning American History, not later than our fourth grade.
I hear stories from the California that was, and wish I'd been around to experience it. What California's become is such an abject shame. How we ever slept through allowing it to be taken over as it has is a mystery for the ages.
