A few weeks before we moved, the big kids made "Happy Land" in the back yard, which included this dangerous and fun attraction.
Bo would ask to go outside to Happy Land every free second he had. Here's his video. And here is Arabelle's. They convinced me to make a run on the slide too.
I let them play all they wanted because I knew we'd be leaving the wobbly play set in town and that would be the end of "Happy Land". :)
