I hope if the klowns rumor is true that Sting Alley does get used again, I mean it hasn't been used as scarezone since Shadows of the Past back in 2009, I can't count KKFOS, that area was block during that time but it'd be cool if it was part scarezone/food booth area or photo op but I can imagine the crazy cluster it'd bring haha.
Simpsons coming to the event in a little mini scarezone shouldn't be too harmless, a couple of looks the simpsons done in the show would be cool, some living dead historical figures from one of the early episodes, and stuff like that would be a nice touch honestly, the music from each respective treehouse of horror episode playing in the queue and in the area would sweet too.
