Header image is a yellow selection button that reads "I'm looking for potatoes to eat," nicked from someone here. Avatar is me, a middle-aged cis white woman dressed in all black, sitting in a sauropod footprint fossil at the Carnegie Museum in Pittsburgh. I'm kicking up one leg straight out, and smiling hard with my white teeth showing and my dark eyes bugged out behind my dark-rimmed glasses.
