Marking the Lane

I rolled past the terrace threshold and hit the sunlit concrete of the driveway. Right across the expansion joint lay a stubby cylinder of blue sidewalk chalk, dusty and waiting. Detours? Out of the question! *Vrr-r-r!* I lowered my excavator boom, locked my jaw behind the chalk, and revved into high gear. *Scri-i-itch!* My rubber treads dug into the rough pavement as I bulldozed straight ahead with full thrust. A thick, vibrant blue stripe unfurled along the gray slab behind my path! *Click-snap!* I eased off the throttle, reversed two inches, and admired the fresh track. Custom-graded haul lane complete!
