Anyone who lives in the Woodland Heights has probably already seen them, the enormous purple and green dinosaurs tromping across the back wall of Travis Elementary. Thanks to artist and parent extraordinaire Dale Barton, the wild mural, a cartoon dreamscape of prehistoric proportions, is the sort of colorful image that kids and grown-ups can ogle for days. In one corner is a Guitarasaurus Tex, an orange, 15-foot-tall, ax-playing dinosaur. Across a blue sky flies a pterosaur, and in between are frogs, butterflies and all sorts of other critters, some real and some conjured by Barton's kooky imagination. Ediface Rex is available for viewing most anytime but when school is in session.
