Summer Daze

On today’s show: We continue our Summer Stuff series with a look at outdoor activities to do in and around New York City. Alex Kotlowitz and “Hoop Dreams” director Steve James talk about “The Interrupters,” their new documentary on stopping gang violence. Then the producers of “The Harvest” tell us about their documentary, which chronicles the lives of child migrant laborers working in the United States. And Please Explain is about how animals adapt to urban environments and what that teaches us about evolution!
