I spent some growing-up years just outside Philadelphia in the 1960s, and I remember strongly some things about that time and place that I saw on the tube. Lead paint warning commercials -- I remember one with a child in a window picking off the flaking paint and eating the chips. Philadelphia was a big gang place -- there were public service announcements-- one with a boy in wheelchair. He'd been shot, and was serving as a warning. Sister Falaka Fattah -- how she opened her house as a safe zone and almost single-handedly changed the city. I wonder if she's still out there doing that. I have admired her for almost my whole life.
