Digging Holes

The other day we woke up to the sound of a crane cracking through the street and the smell of donuts (from the cop detail). The crew dug about 8 holes on our street and many more throughout the neighborhood. Shortly after digging, they haphazardly filled the holes back up again with asphalt. Later that day, a smaller crew came back and redug some of the earlier holes to refill them again. They've been back at it the last two days. No idea what they're working on other than job security.
