Playground Workouts?

Question: Does anyone happen to have a good playground circuit training workout routine? Or suggestions of how to build one?

I recently moved, and this moved resulted in my losing access to the gym + the ability to workout at home (other than weight lifting). I used to do the majority of my exercise at home (p90x, body revolution, etc.) with supplementary cardio at the gym, but now those options are gone.

I do have a playground & park right by my house, though; so, until winter, I could make this work. Any ideas?? I see everything except swing set (jungle gym, plenty of bars, small ladders, slides, and a large enough grassy area to run laps around).

I really work best with structure/routine, so if I could set up circuits with this space/equipment, that would be awesome. At least until December, when I would have to find someplace indoors for the winter.

Thanks!!
