"My face looked like it had been jammed into the spokes of a speeding Harley, and the only thing keeping me awake was the spastic pain of a broken rib. It had been a bad trip. . . fast and wild in some moments, slow and dirty in others, but on balance it looked like a bummer. On my way back to San Francisco, I tried to compose a fitting epitaph. I wanted something original, but there was no escaping the echo of Mistah Kurtz' final words from the heart of darkness: "The horror! The horror!. . . Exterminate all the brutes!""
