The Herald of Rock Hill reported the electronic signs on state Highway 160 near Fort Mill that usually warn of traffic construction or wrecks had a very different message Sunday.
One sign read "Zombies Ahead" and then flashed "Watch for Hunters." On the other side of the road, a sign warned motorists to "Be alert for Tanks."
Department of Transportation resident construction engineer Ken Wilson says a key is needed to get into the control box for the signs and a code is needed to change the wording.
There have been no reports of zombies or tanks.
