Terrible experience! Today there was a "game tonight" sign that had rolled across the street multiple times. On one of the occasions I had run out of my office to stop the sign from hitting a vehicle and the sign had ran over my leg in which I was bleeding. Called the office and staff were very rude on the phone when explaining what had happened. I just wonder what would have happened if it hit a car or even if I had fallen on concrete.
