Presentation Zen: We learn from stories and experience
by Scott Smith
Of course, people often ignore warning signs like this or think that the dangers are abstractions that happen to other people, if they happen at all. What I found very effective was that the park service included real newspaper clippings of actual deadly accidents that had occurred there recently. I know it was effective because people read these articles and you could see the look of concern on their faces. I usually would only glance at such signs, but I stayed there and read every word.
