speaking of "wearing headphones while biking is bad....mmmmkay", I was riding the other day with my kids in the tandem trailer on a bike path. Came up on the kid from behind fumbling around with his ipod while walking. I kept trying to get his attention to move out of the way but he couldnt hear me. I had to go nearly off road to get around him. Think he got a lil mad, I was too. So I dont want to head about safety issues with wearing headphones while biking, same exact thing can be said bout walking also.
