Coming Down The Pike

The word “turnpike” got its name from guardsmen standing at either side of a road and lowering their poleaxes to block the road until a toll was paid or a pass was shown.
These days, the pike has been replaced by a mechanical barrier or by cameras which scan for an electronic toll-paying device and capture the license plate numbers of violators.
Still, somewhere in that tollbooth, there’s a fierce-looking halberd leaning against the wall.
When the machines fail. Society breaks down, and the zombies win.
The tolls must be paid, and they certainly don’t collect themselves.
One brain please.
