In the movie "Easy Rider", where did Wyatt and Billy hide their money?

"Easy Rider" is a 1969 American road movie written by Peter Fonda, Dennis Hopper, and Terry Southern, produced by Fonda and directed by Hopper. A landmark counterculture film, and a "touchstone for a generation" that "captured the national imagination", Easy Rider explores the societal landscape, issues, and tensions in the United States during the 1960's, such as the rise and fall of the hippie movement, drug use, and communal lifestyle. In Easy Rider, real drugs were used in scenes showing the use of marijuana and other substances.

The protagonists are two freewheeling bikers: Wyatt (Fonda), nicknamed "Captain America", and Billy (Hopper). Wyatt dresses in American flag-adorned leather (with an Office of the Secretary of Defense Identification Badge affixed to it), while Billy dresses in Native American-style buckskin pants and shirts and a bushman hat. The former is quite open to people they meet on their journey and accepting of help while the latter is more hostile and suspicious.

After smuggling cocaine from Mexico to Los Angeles, Wyatt and Billy sell their haul to "Connection", a man (played by Phil Spector) in a Rolls-Royce, and receive a large sum in return. With the money stuffed into a plastic tube hidden inside the Stars & Stripes-painted fuel tank of Wyatt's California-style chopper, they ride eastward aiming to reach New Orleans, Louisiana, in time for the Mardi Gras festival.
