You're standing directly under the Gateway Arch in St. Louis, MO, USA. You look up and note that the sun is directly above you as well. Suddenly, you notice the Arch begins to sway, and you realize that it's going to tip over. However, you don't know which way it is going to fall, and because of the sun it's too hard to see. (Not to mention the watery eyes you have from looking into the brightness of the sun.) A few other people see it too, and as they begin to scream, panic breaks out. Tourists are running wildly everywhere. If you run the wrong way, you know you won't have enough time to go back the other way because the crowds are so insane, and you wouldn't be able to break out of the crowd in time. Which way do you run?
