"Max said there was a gnome in there so I have to find it."
I don't think we are still at the point where we have to argue about the benefits of natural environments and free play. (If you disagree, this is a great place to start reading.) Inspired by a few links at the Children and Nature Network, I discovered a dandelion meadow of links on how to create amazing, inspiring, and bodacious natural playspaces and playscapes. All the links lead to PDF printables. Enjoy.
