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.
