5. Pretty Much Any Square Inch of Sunnydale - Buffy the Vampire Slayer
Sunnydale Highschool has a higher body count than a John Woo film. And no one ever seems to care. Now, given that Sunnydale is on a Hellmouth, it's definitely not the number one hot-spot to take your kids for a Halloween spectacular. Unless of course, you're seeking your children to be abducted by vampires and turned into prophetic entities for the destruction of the world. Because if that's what you're looking for, then you won't find a better nursery that is Sunnydale. And even though it's got a protector in Buffy, she shouldn't be responsible for your stupidity. Just take your young'uns literally anywhere else in California for their treats. Anywhere that isn't on this list, I mean.
