Summary: On this week's Allegheny Front, fifth graders cruise Pittsburgh's rivers, learning about ecology outside of science class. And which native fruit seems more at home in the tropics? We'll talk pawpaws with a writer who has become an ambassador for the forgotten fruit. Plus, a photographer captures moments when he and an animal take each other by surprise. All this, and more. http://media.alleghenyfront.org.s3.amazonaws.com/AF062213Show_0.mp3
