Children's Playground Adventures
Children (and husbands) like mine might be the reason that the more “dangerous” playground equipment is usually not what is found at playground these days.
Or you could read Barefoot and Balanced. Then you might call it hand strength and vestibular stimulation and positional awareness and outdoor time... Or just having a fun time with your Daddy and a slow motion iPhone camera.
While barefoot, of course.
A bit of shin skin was harmed in the process. But he would declare it worth it ;)
