So ... I go outside because I hear (and smell) the MAC truck from where I was inside the house.
And I say to the one not in the truck, "What is he doing in the truck?" (So far, I've seen going down the driveway, coming up the driveway, backing, parking, pulling up to another spot ... it seems pretty random to me.)
The one not in the truck says, "He's takin' it for a spin!"
For a spin.
Taking a dump truck for a spin.
I think summer's coming.
