Years before launching the CISO Series, our own David Spark was a San Francisco resident and lover of San Francisco history.

After spending a month at the San Francisco Public Library pouring over old news articles to write “Nude, Lewd, and Crude: The Rise of Strippers, Beats, and Comedians in San Francisco’s North Beach from the 1950s to 1970s,” he became a San Francisco tour guide where he led walking tours, joked and played games with tourists, and handed out misfortune cookies (A precursor to our “What’s Worse?!” game).

It’s been 15 years since Spark last led a formal tour and he’s looking forward to doing it again with you on the very last day of RSA.

WHEN: May 1st, 2025. Assemble at 7:30 AM. Tour starts sharp at 8:00 AM. Tour will last 75-90 minutes where we’ll end up the at W Hotel for breakfast
WHERE: In front of Vesuvio’s Cafe, 255 Columbus Ave., San Francisco, CA (map) on Jack Kerouac Alley.
