Day one there were two on the ground chipping and trying to enforce the do not enter DANGER signs. The second day was not as bad (maybe the people listened to the lecture why it was a bad idea to ignore the signs and went 100 ft out of their way to avoid the work area) The average person never looks up and even if they do they can't seem to comprehend the danger. In the future I might build another person into the bid to handle work zone enforcement. Maybe get some of John Ball's slides to hand out to help reinforce the point.
