The Free Play Network have created an online exhibition of play spaces, categorising them into places of woe and possibility. It's depressing to see the places of woe, as you would expect.... but for me more because we all know places that look like that, rather than for the obvious reasons.
The places of possibility have one common theme.... nature.
Back on my soap box again....... it's a fine place to be. Good views and a little wind in my face.
