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