Walking with Superman: Day 358

When random text messages with similarly irreverent and strange content go out to random area residents, the police blamed it on pranksters. But when every electronic device in the area, from car GPS units to 911 dispatch computers, starts displaying nonsense messages instead of information, residents rightly begin worrying! Superman puts his skills to the task of tracking down the heinous hackers, but the truth will shock even him!
