I want to make everyone aware about a free app called Natural Playgrounds that is available on iTunes. The app has a map with locations to find Natural Playgrounds. It is a GPS linked map so you can find locations and directions to natural playgrounds in your own area or an area that you are visiting. The map has only about 30 natural playgrounds listed at the moment because the app just came out but all of you can email more locations: it is a growing map that maps the growing natural playgrounds movement.
Have fun with it!
