Joel had a post up about how-to change the message on construction signs. Well, hackers in Austin, TX wanted to see if it worked, and it did! Apparently its a pretty big misdemeanor and it endangers the public, but I still get a kick out of it! I would always wonder what would happen, or what would be my plan if Zombies attacked. What if, one day the signs are telling the truth! Well, if you have an interesting Zombie Escape Plan please let us know by posting a comment.
