Apple Thoughts: Use Trapster to Find Haunted Houses As Well As Speed Traps

"Halloween, with its legions of black-clad kids running around and darting out into the street, introduces its own variety of driving perils. So in addition to warning other users of speed traps and red-light cameras, Trapster users can now mark two new location types on its map this Halloween: haunted houses and trick-or-treat zones."

And before you think you can play some tricks on your friends and neighbors by marking their houses as "haunted houses," bad information can be removed with enough votes. Of course that will take some time so it still might work as a trick, although it's supposed to be used for good not evil folks!
