Previously I posted about a film called "The Apology." I went to see this film yesterday and thought it was really well done with an important message. I recommend it highly, not only for tour guides, but for the general public. For more information about the film, see the website.

On Tuesday 9/17 there's another free screening of the film, with a panel discussion, in Castro Valley. Sorry for the late notice. Details here: https://patch.com/california/castrovalley/calendar/event/20240917/db7056fa-66d0-4639-89b6-4123074388cc/the-apology-documentary-film-with-panel-discussion
