I would nominate "Dead Acres" Pataskala Ohio
my reasons are
They are the most extreme
Nearly everything else pales by comparison.
It doesn't get much better than this!
LENGTHLY - good value !
ACTORS - Aggressively intense from start to finish !
SCARINESS - You'll fear for your life! Numerous distractions provided by a boat load of animated props are perfectly capitalized upon by the energetic cast. Very little in the form traditionally spooky music, but the soundtrack is designed to compliment the intense nature of the haunt, which it dramatically accomplishes.
PROPS - Jammed with an overwhelming number of animated scares!
SIMPLY THE BEST EXTREME HAUNT WE HAVE EVER HEARD OF !
