I’ve been to San Francisco 5 times and have witnessed 10 public dumps.
Man vs parking meter while getting a ticket
Man between 2 police cars
Man vs the Pier
Woman in a dress outside a bar puking into a car window, business end to the street
Woman outside a liquor store near the Giants stadium
Man vs open guitar case
Large human in a dress and heels, I’m assuming in self defense, when unable to run away after an exchange of goods gone wrong
Man in the lobby at the Grand Hyatt
Woman vs trolley tracks
Man between busses after the Kraft Hunger Bowl - 68% sure it wasn’t me
Oddly enough, in my experience the public dump per visit ratio has also been 2 PDPV in places like NYC, Austin, Salt Lake, Orlando and Las Cruces, so I figure it’s just status quo. It’s also possible I need better tour guides/new friends.
