Obviously somebody's version of a practical joke, hackers took to the road (sign) and put in their own message on a warning sign.
Flagstaff police reported the road sign on Fort Valley Road was hacked and the message put in instead of the usual warning sign of "no left turn at next intersection." It was reported to the Arizona Department of Transportation at 3:00 a.m. and fixed by 11:00 a.m. Monday.
There are currently no suspects to the hacking but special equipment would have been necessary to do something like this to state property. Officials did say there was no threat to the public from any rogue Pandas.
