Hey, the folks at kaBOOM! are the real deal, getting lots of playgrounds built at places like low-income schools.
New projects include a crowd-sourcing effort where everyone can pitch in and identify playspaces on maps for everyone.
I spoke days ago, and here you see the staff showing what they found on craigslist, like "job", places to live, and lots more.
Check out their site, and consider adopting a playground. I'm planning on that now, one in my neighborhood. More later…
