NBC NATIONAL NEWS — Vandals have repeatedly broken into a portable electronic messages board left on the side of a construction zone in Placer County, California and switched the message.
The first time it read: "Caution Loose Gorilla," according to residents who live in the area.
The message boards are supposed to warn drivers that Wells Avenue will be closed soon for construction.
Instead, the message boards are being reprogrammed.
The second prank message read "smoke weed everyday."
More vulgar messages followed.
