Playing with building supplies

We were at my wife's mothers home helping her clean up the yard and surrounding grounds.  While we were there my kids found these old construction tubes for irrigation or cement or something.  They were to cool not to play with so they taught themselves to walk on them much like a lumberjack on a floating log.  I tried it...off camera.  The only person who was happy I even tried will be my chiropractor.  This is definitely a young persons sport.  I really like the evolution of using the battle baton to knock each other off.  Great lesson on adversity in all things.
