Vandals in three US states have altered the text on electronic road signs, posting notices of "Nazi zombies" and "raptors ahead" instead of legitimate messages detailing traffic problems. The latest prank took place Tuesday in Collinsville, Illinois, and warned "DAILY LANE CLOSURES DUE TO ZOMBIES". Past faux warnings from around the country this week include: "NAZI ZOMBIES! RUN!!!", "RAPTORS AHEAD.", and "ZOMBIES IN AREA! RUN." As you can imagine authorities don't think hacking traffic signs is funny and warn that doing so is against the law punishable by removal of your delicious brain.
