From Paul Hiffmeyer of Disney Parks Blog:
Continuing my Cars Land road trip with Lightning and Mater, I caught up with them over by Radiator Springs Racers. This stretch of road has one of the best views of Ornament Valley – and it’s a great place to set a spell and watch some racing.
Then I caught up with Mater outside Mater’s Junkyard Jamboree where I think he had hoped to find a hidden Mickey, but apparently he never saw one. Oh well. Keep looking, Mater.
