Mine used to play outside when there were quite a few other local kids playing out so they could all keep an eye on eachother, very rarely now though, as numbers have dwindled for some reason, so they tend to stay in the garden. I disagree with the point about going to the park, when my chidren played out I could watch them out of the window, and hear them, if they 'walked 10 minutes to the park' I wouldn't have a clue if anything had happened to them.
