While former president George Bush’s new house is in Dallas, folks in Austin–195 miles away–were so concerned about zombies that roadside alerts went up.

Austin residents were surprised to construction signs warning them:

Zombies In Area! Run

The signs are not owned by the city of Austin, but rather leased from the construction contractor. However the city is responsible for the messages. The padlocks on the two signs appeared to have been cut and the password protected computers hacked in order to create the anti-zombie warnings. Austin Public Works spokesperson Sara Hartley said:

Even though this may seem amusing to a lot of people, this is really serious, and it is a crime. And you can be indicted for it, and we want to make sure our traffic on the roadways stays safe…The big problem is public safety. Those signs are out there to help our traffic on the roadway to stay safe and to know what’s coming up.

There are  several online sites that teach people how to break into these construction signs, plus a book and numerous instructional videos that inform the public how to deal with zombies.
