It also depends on where you live. If you are a suburban or rural kid, playing outside all you want is fine. Let them explore the neighborhood. If you live near a highway though, or a high crime area, then you might want to reconsider what you want to allow. You still need common sense.
My main worry is people who live in relatively safe areas, like a suburban neighborhood, but with neighbors that will STILL call CPS on you for allowing them a little freedom. When I was a kid living in a trailer park we had neighbors like that. Never called CPS, but definitely complained about us being unsupervised despite the fact that the speed limit was a mere 15 MPH, and that we made a point not to bother the neighbors because our parents told us not to. They just saw kids playing and having fun, and decided it was a crime against humanity.
