When the dust gets thick on the back window of his Mini Cooper, Scott Wade uses it as a canvas to create temporary works of art. Wade used his finger and other implements to etch this homage to Vincent Van Gogh's 'Starry Night' and Leonardo da Vinci's 'Mona Lisa.' Wade lives off the unpaved Roadrunner Road north of San Marcos, which dusts the back windows of his car and gives him the canvases to create his own works of art. A portrait of Kinky Friedman on the back of the Mazda driven by Wade's wife, Robin Wood, was featured on the gubernatorial candidate's Web site. Wade's creations attract admirers wherever he goes. Who needs a frost-covered window when you've got road dust to create a Christmas scene? Besides his finger, Wade uses traditional art tools, such as paintbrushes, and unconventional ones, like a chewed Popsicle stick, to make his drawings. Wade takes pride in his creations, but he knows that with one good shower, his work will just wash away.
