Construction Zone

The family I provide childcare for is in the process of building a new house.  Oftentimes, after I pick up the boys from preschool we drive by to check out the progress.  Today was a cold, windy day, but it was sure exciting!  We got out and watched for almost 45 min. while the giant excavator dumped rock into the hole while other workers set forms for the foundation.  When it got too cold, we watched from the van.  I love the first picture.  What caption would you put on it?
