In the December 2019 issue of National Geographic magazine, photographer Corey Arnold writes about an expedition last winter to change the batteries in the radio collar of a black bear in Utah’s Bryce Canyon National Park that he assumed would be hibernating. The bear turned out to be awake, which made the adventure more adventurous than expected. Write a short story in which your main character is operating under the assumption that an upcoming activity will be safe, but at a crucial moment discovers that danger is lurking. How do you ramp up the sense of anxiety and tension? Does your protagonist respond calmly or with panic when confronted with a sudden terror?
