"Germany has adventure playgrounds that are stocked with scrap lumber, nails, and hammers, so children can come and build things, and then tear them down and build something else." No it doesn't. As the parent of a six year old in Munich, I would have noticed. (OK, I can't speak with total authority on every single adventure playground in Germany. But I can say that what the author is describing certainly isn't the norm) The general point, though, is valid. What Germany does have is proper playgrounds with proper things to swing and climb on at heights from which a small child could hurt itself, not the ridiculous little six-inches-off-the-ground things I've seen on visits to new York.
