I'm kinda of guilty of the helicopter mom thing (though in my case it's moose, bears, and wolves I worry about, not really kidnapping, though I don't like the renters at the end of my street cause they blow through here at 45-50mph like assholes...) BUT even so I started letting my youngest walk to the school bus stop a good block and a half away [in the dark qq] from the house around 4th grade. It was his choice, I'd been driving them to school everyday, but he wanted to ride the bus with his friends and "debate stuff." I used to drive him down to the bus stop and sit in the car while they yapped, but that wasn't appreciated either.
