I love what you’re doing in SF!!! It seems like your kids have a great life, and you’re doing great things for other kids, too. I would definitely like to visit sometime. I wish we still lived there so we could join you, but we moved to Palo Alto from SF two years ago to find kid heaven in the ‘burbs. We’re still looking…
Re your comments on play in nature versus play in neighborhoods, I have a couple of comments. First, kids in suburbs and rural areas often have woods right by their house, so these aren’t necessarily contradictory. I know I did when I was a kid. Second, if the play’s not by the kid’s house (i.e. in or close to his or her neighborhood), then usually a parent needs to plan the play and provide transportation. This often taints the experience for the kid because it has to be scheduled, and ultimately, the parent usually ends up monitoring the experience and controlling it somewhat.
Your organization may be eliciting different behavior from parents - I certainly hope so…
