Thirteen and Root of All Evil have both
been removed from the Howl-O-Scream website.
Judging by the teaser they just posted (below), I assume we're getting a Root of All Evil replacement.

Breaking News: Maintenance Crews Stopped in Tracks - A construction team was halted yesterday when crews hit upon a mysterious object while digging in a back area at Busch Gardens Williamsburg. The park is currently investigating the unusual discovery. Please check back for more information.
Glad to see Thirteen missing, but Root? Why remove the park's best house?
