Dyke bars are not new.
There used to be a bar in Mountain View, California on El Camino Real called “Daybreak.” One day long ago (like 1979), I was riding home from work on a hot summer day and decided to stop in for a beer. It didn’t take me long to notice that ALL the patrons were women. I thought I’d died and gone to heaven.
Then I thought it peculiar that not one of them paid me any attention and my efforts to kindle conversation were rebuffed. It FINALLY dawned on me what was going down. That was my one and only experience with a dyke bar.
