I remember this as well, the one I could quickly find was an NPR article[0]. The key difference between what you're mentioning and the article here is "buildable risk". i.e. the kids build the playground and it's age appropriate for their abilities. The article, more the photos in the article, look like death traps at height. Even self-built playgrounds won't reach those crazy heights.
