Today, we had this happen outside work on Antigua Street:
The dump truck was trying to unload its load, and, while it was driving forward to do this, the top of the dumper struck the powerlines hanging across the road, pulling the top of the power pole on our side of the street off. You can see it hanging down by the pole in the centre of the picture.
Thank God, no one was injured. The driver and construction workers are all okay.
Lesson learned: Always pay attention to your surroundings!
