The Most "Feared" and Haunted Day of 2008 HAT

We could have held this story until tomorrow, Friday the 13th, but we wanted you to have ample time to stock the larder, bolt all the doors and windows and hunker down until the dangerous 24-hour period has passed. Then, of course, you can come in off the ledge. Or can you? What makes Haunted America Tours refer to tomorrow as "The Most Haunted Day of the Year"? On the other hand, you might want to debunk the entire notion with a trip to HowStuffWorks Reveals the Secrets Behind the Superstition of Friday the 13th.
