Raoul Duke: We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember saying something like:
Raoul Duke: I feel a bit lightheaded. Maybe you should drive.
Raoul Duke: Suddenly, there was a terrible roar all around us, and the sky was full with what looked like huge bats, all swooping and screeching and diving around the car, and a voice was screaming:
Raoul Duke: Holy Jesus. What are these goddamn animals?
Dr. Gonzo: Did you say something?
Raoul Duke: Hm? Never mind. It's your turn to drive.
Raoul Duke: No point in mentioning these bats, I thought. Poor bastard will see them soon enough.
