Once upon a time…
There was a writer named Ray Bradbury. In 1952 he published a story called “A Sound of Thunder.” It was about a hunter named Eckels, who payed big bucks to a time machine company called Time Safari, Inc., to travel back to the time of the dinosaurs to hunt T-Rexes. Only animals that are just about to die are selected as targets, and the hunters can shoot them moments before death.
Travis the guide explains that hunters must strictly obey their guides and “stay on the path,” an anti-grav walkway that touches nothing, as touching anything at all in prehistoric times could have huge evolutionary impacts rippling up to the present day.
As they leave the futuristic present for the ancient past in their time machine, Eckels remarks that he’s so relieved Keith, the liberal candidate, was winning the election. Soon, the men arrive in the midst of a jungle that existed 60 million years ago.
