The plight of Route 66, whose removal from the United States Highway System in 1985 turned places like Glenrio, Texas and Amboy, California into overnight ghost towns, has captured public attention. Route 66 associations, built on the model of Angel Delgadillo's first 1987 association in Seligman, Arizona, have advocated preservation and restoration of the motels, businesses, and roadside infrastructure of the neon era. In 1999, the National Route 66 Preservation Bill allocated $10 million in matching fund grants for private restoration and preservation of historic properties along the route. The road popularized through John Steinbeck's "The Grapes of Wrath" and Bobby Troup's "(Get Your Kicks On) Route 66" was marketed not as transportation infrastructure but as a tourism destination in its own right.
