There must be a reason why popular culture -- from Interview with the Vampire to True Blood to The Vampire Diaries -- has associated vampirism with the decaying Old South.
Maybe it's the humid heat and hint of sultry sexuality, or the decrepit mansions, or the voodoo tradition, or Southern gothic fiction from Faulkner to O'Connor to Capote.
Okay, Dark Shadows is set in the Northeast and Twilight, the weakest of the bunch, in the Northwest, but y'all are vampire central. Tell me Jefferson Davis didn't look and behave like one of the Undead.
