As cartographer Denis Wood wrote in the provocative 1977 essay "Free the Children! Down with Playgrounds!": "A playground only makes sense if adults know better than kids where, when, and with what to play. But if kids know best — and everything suggests they do — than the adult construction of playgrounds is senseless."
"Children are a kind of indicator species. If we can build a successful city for children, we will have a successful city for all people." —Enrique Penelosa, pioneering urbanist mayor of Bogota, Columbia.
