CINCINNATI, Oct. 11 (UPI) -- An electronic construction sign baffled Ohio drivers with a mysterious and apparently fed-up message reading, "Blah Blah Blah Blah Blah Blah."
The sign, located on Elm Street by Cincinnati Music Hall, left drivers perplexed Monday evening when it read a series of Blahs instead of information on upcoming construction or traffic.
The Ohio Department of Transportation said it was unaware of the message's origins, but overhead signs on nearby highways appeared to be unaffected.
Police said they had not received any reports about the sign.
It's not known what message was displayed on the sign before the "Blah Blah" showed up.
Electronic construction signs are frequently targeted by hackers who reprogram them with occasionally humorous messages including warnings about attacks from zombies, angry gorillas and movie monster Godzilla.
