Just for the hell of it, he decided to break the speed limit on the flat, straight road back to the heart of the sprawl. Roaring along the riverbank, he seriously startled some students poling flat-bottomed punts along the River Cam, but none actually fell into the stinking water. Serrin had read in his guidebook that ingesting a mouthful of the river water gave you a flat 10 percent chance of death by chemistry, while sometimes a puntful of students got swallowed by one of the paranimals that wandered downstream from the Stinkfens to the east. But the students still went on punting, as if the simple tradition of it all could defy the realities of a ravaged earth. People just went on: punting on rivers of filth, buying demitech that’d kill them more times than it’d work, going to butchers to get questionable cyberware implanted in street clinics, believing in another green guru with a smile on his face and a corporate credstick stuck up his ass.
