Zombie signs back from dead - in Oregon

PORTLAND, Ore. (NBC) - Another traffic sign warning drivers of zombies ahead has popped up, but this time, it is in Oregon.

Motorists in Portland saw a contractor's sign Wednesday near the Ross Island Bridge.

A prankster apparently accessed the sign's controls and typed in the message "Caution Zombie Strippers."

The sign was spotted by officials and turned off Thursday.

The prank is old news in Austin, where hackers in January changed the toll sign on MLK to read: "Zombies ahead" and "The end is near!!" The story made headlines around the world, touching off a few copycats throughout the week.
