In the 90s, every year during my school's spring break I would go to my dad's office in downtown San Francisco. I was too young to be alone all day.
There is a fountain that survivors of the 1906 earthquake would meet at on the anniversary of the event. Because my spring break cooncided with the date, I got to see the survivors gathered as my dad and I walked to his office.
Of course there were already very few survivors left by then. I think I would have seen it around 1994 through 1998 when I was old enough to stay home on my own. Even in those few years, I could see the number of survivors shrinking.
