In the town of Kirkland decided to fight for the safety of pedestrians. Pedestrian traffic lights put expensive and inefficient for the three pedestrians per day, which generally are in American cities. Instead transitions hung from two ends of a bucket with bright yellow flags, officially named the sonorous word pedflag. The idea is that you need to take the yellow box in a bucket on one side of the street, go and put it in a bucket on the other side. But as idiots just go with the flags even Kёrklande not found, then each bucket had to write the following mathematically precise inscription: "62 people in the city Kёrkland suffered or died at pedestrian crossings. Of those with a flag - 0 ».
Today, flags are used instead of the traffic lights in Seattle, Salt Lake City and Berkeley.
