The Prospect Park Youth Advocates get some well-earned star treatment in this Streetfilm from Robin Urban Smith. They spent the summer gathering data and collecting signatures for a car-free park, culminating last week with a rally at City Hall. Now we see what it takes to mount a 10,000-letter petition drive: resourcefulness, persistence, and the self-possession to wear a leaf costume with aplomb. Bravo to Farah, Oswald, Selena, and Michael.
