Road work

A week ago I was rudely awakened at 7am by the sound of a jackhammer and large equipment...and the annoying beeps they make when put into reverse. Did I mention that it was 7am? When I finally dragged myself out of bed, resigned to not being able to get back to sleep and looked out my window, I was greeted with this site. They worked all day, tore up a patch of road about 20 x 8 fixed whatever was broken, and laid new asphalt before driving off at 5pm. How can construction workers always look like they are doing nothing and yet get stuff done? I swear each time I looked out, there was either no one in sight or they were all standing around talking! One of life's great mysteries I suppose!
