Arrows, Arrows, we don't need no stinking ARROWS. I mean who really follows the Arrows?
AMEN.
I have NEVER paid any attention to the arrows on the floor. Have we become so dumbed down that we have to rely on arrows on the floor to tell us which way to walk? Good grief. The crowds these days are no where near large enough to warrant "traffic cops" in the orange hall.
As for the weather forecasts...I've been an active commercial pilot since 1983. As a pilot, accurate weather forecasts are important to me. I can tell you without any reservation whatsoever that aviation weather forecasting was more accurate back in the 80s and 90s when flight service station staffers actually went outside and OBSERVED the weather. Today it is all automated with wind speed and direction sensors, infrared sensors, temperature sensors and the like feeding into a huge network of computers. The forecasting accuracy is not what is used to be...not by a long shot.
