In his usual persistent style, Michael managed to procure from David the purchase of scrap lumber (half off!), which he immediately turned into a go-cart. He's had this design in mind for quite some time, so it only took a few hours to put it together. It's just about perfect for the long, slow slope down our street (also used for sledding when we get the occasional winter snow).
This particular go-cart must be ridden accompanied by sound effects courtesy of Bill Cosby.
