This is fascinating. John Lasseter and Dan Scanlon provide director’s commentary audio about the Pixar animated short, “Mater and the Ghost Light,” which came out during the DVD release of the 2006 Disney-Pixar film “Cars.”
They prominently mention Eisler Bros. Store (aka Old Riverton Store) in Riverton, Kan., on Route 66, and “Route 66: The Mother Road” author Michael Wallis during their remarks.

“Mater and the Ghost Light,” as Lasseter mentions, is inspired by the Spook Light phenomenon just off Route 66 near the Kansas, Oklahoma, and Missouri state lines.
Waylan’s Ku-Ku restaurant in Miami, Okla., still provides maps to customers if they want to check out the Spook Light for themselves.
