Not a somersault on top of it-guess that could be misread!

This one was sort of like a stack of open cubes built of pipes. The cubes were about 24" square, so as a child, it was easy to do a flip on/around one bar (like doing a flip on uneven parallel bars), and not hit my head. As an adult, well, I had a lovely bruise!

I was a monkey when I was a child-always up a tree, on the jungle gym, the slides the swings, climbing up in my grandparent's barn....
