The boys have been reconstructing the highways and byways in our house. Just like the new roads in the neighborhood, we've had construction equipment making noise and wandering all over the place. When you're done, then you'll need to clean up the worksite.
A job well done is its own reward.
The boys like to chase each other around the loop, each of them using a dump truck as an aid. The picture of Adam was intented to get a look simiar to Mark at the same time (I couldn't find the same hat before the 'timer' expired and someone insisted we go outside).
