A prankster is changing the message on an electronic traffic warning sign in Northern California.
The sign is supposed to tell people that a road in the Placer County city of Loomis will be closed for pipeline construction.
Instead, it read, "Smoke Weed Everyday" last week. The Sacramento Bee reports (http://sacb.ee/ZKeX8l) that it has also read, "Caution Loose Gorilla!"
Placer County Water Agency Senior Engineer Tony Firenzi told the Bee it took skill to change the message. The unknown hacker needed a keyboard and had to bypass some systems.
