Natural Outdoor Playspaces | Musings Great Idea!! would be a perfect idea for the side of the ouse - no one can see it but the kids would have a blast with it! could be put on heavy hooks to put away in bad weather.
Ideas on how to make your own "almost-free" outdoor playground. Somehow, I think my kids would be more inclined to play with a rubber tire than with the ugly plastic thing that they have in the backyard right now.
