I was thinking that, East from Downtown Radiator Springs, at where usually there is a thing to use to get to the Piston Cup Locations, there should be a location called Ornament Valley. At Ornament Valley, there will be the Rustbucket Stadium, which the race track in that location. Mater can be racing there. He could also be seen in front of the race track. There should also be the 5 mile billboard for Radiator Springs, and Sheriff should be seen there. There should also be a mine, which is connected to the mine at the Wheel Well. Maybe both mines could be one mine. Also, there should be a mountain area, and a train yard, and Ornament Valley Airport, which you can use to get to the World Grand Prix locations. There should also be the white arrow which you use to get to the Piston Cup locations.
