Magicians or the handy work of a hacker?

It appears somebody over the holiday weekend hacked an electronic construction sign at Folsom Street near the intersection Canyon Boulevard. The sign on Monday read: "MAGIC IS REAL."

Last year, hackers tweaked a Boulder sign to read "WARNING DALEKS AHEAD," referencing a villainous race of extraterrestrial mutants from the British sci-fi TV series "Doctor Who." And, in 2011, pranksters hacked a sign along Foothills Parkway so it read: "Zombies Ahead."
