A heated debate has emerged in parenting circles: Should kids be allowed to walk to school? In 1969, nearly 50% of kids walked. Today, that number has dropped to 13%, with many parents arguing that it’s just too dangerous nowadays to let kids walk. Are they right? The Takeaway's correspondent, Andrea Bernstein, was at the Walk21 NYC conference yesterday in New York to talk with people about urban planning strategies for city walking. We also talk to Gina Lovasi, from Columbia University's Mailman School of Public Health, about the health implications. Jeremiah Weintraub, a fifth-grader from West Virginia who's been riding his bike to school for over two years, joins us with his thoughts on the matter.
