I went to an old movie theater in the Castro for a film festival, and arrived before the show started. Was extremely startled when they showed vintage gay porn before the main feature started, like, where most theaters run that "noovie" waste of time. It was cute but what a surprise!
Later I went to find someone else who had been at that theater to confirm I didn't imagine the whole thing, and to convince them to talk with me I cooked them breakfast, and one of them spent the whole time making fun of my cooking and technique. I was unperturbed.
I wonder if there IS a theater like that in the Castro, or was. I was only there once in a blue moon, I never did much exploring. When I went goofing off in SF I was either in the Haight or the Mission.
