“Oz” as in Ozarks, has become a common theme throughout Northwest Arkansas. The mural is the journey in search of OZ, the emerald city, finding the beauty of what is already here. The yellow and green sections leading toward the top of the tunnel signify the yellow brick road and the poppy field in the movie ‘The Wizard of Oz’. The flat small area at the top of the tunnel has green towers with vertical mirror signifying the destination.
