Late Night Work?

Ok, so I just took this and I know it's not the most interesting picture but I had to comment on it. These workers were here through the ENTIRE night preparing the roads for paving. I have never witnessed construction workers with this kind of shift. It struck me very odd. Were they noisy? Yes actually they were. Beep beep beep and loud crunching sounds as they ripped up the old pavement. I had the air conditioner going though so at least I didn't hear them when I went to bed but they were definitely there. So of course, because I have the day off here...they would be here making noise. So much for my semi peaceful java on the deck this morning. *sigh*
