I nominate my father for the Earth Day gold medal. He repairs whatever is broken and figures out how to use anything obsolete. I have seen him cut his own key for a defunct golf cart, fashion a back windshield for his car from Plexi-glass and scraps of wood, and clean sludgy sewing machines out with an air compressor.
He is the king of buck-sheeing, hay-wiring, and jiggy-pooing. And he's kept his old dog chugging along for over 13 years.
