Have you wondered why kids are jumping a lot higher these days than 50 years ago? Remember when we didn’t have foam to jump in so we used the softest things we could find like sawdust, at our school! I have heard others speak of straw bales and sand! I was in the eighth grade when we got our first net bag filled with giant foam rectangles. That was a real improvement! What did YOU high jump onto?
