My dad's in contruction too and is quiet.
Our business tends to stay level - but when construction is booming it REALLY booms.
Our driveway is about 100 yards long and around a 30% gradient near the top - not much can be done to it by JJ methinks! Flipping lethal walking down it in the wet.
Oh and the ad budget wasn't going to us - we just charged hours for the "coordination" time. Oh well.
