As a child I was always frightened when we went camping, as we had to drive through a canyon to get to our usual spot. I was convinced a large rock was going to detach itself from the canyon wall and crush our car. I wasn't afraid of real canyon dangers, such as a flood or landslide, just a huge random boulder.
