The Playing Out group say that 57 Councils are now actively supporting schemes that help children to play in their street with their neighbours.
Playing Out is a great charity that came out of the street party culture in Bristol.
They developed a practical way for temporary play street traffic orders which allow kids to regularly play safely, supervised by adults closing the road.
The good news about the spread of this idea can be read on thier blog here:
