Well, moving past the whole "witches are going to poison your kids on Halloween" myth. (They aren't. Seriously.) There's actually a REAL and more present danger out there...the sex offender. They are all over the place, they are your neighbors, they work around you. So before you take your little ghosts and goblins out in search of a sugar high, don't forget to check out your local Megan's Law site. Especially if you are heading to a relative's house (as I am), and you don't have a good idea of the neighborhood.
And it might not be a bad idea for you to check out the list, if you're a single lady or ever walk alone.
