American Graffiti [SEP] Inspiration

Lucas embraced the idea, using his early 1960s teenage experiences cruising in Modesto, California. "Cruising was gone, and I felt compelled to document the whole experience and what my generation used as a way of meeting girls," Lucas explained. As he developed the story in his mind, Lucas included his fascination with Wolfman Jack.
