So basically every section of the Harvest will be a different IP I'm guessing. Obviously the TrT section has Sam's fire pumpkin and a school bus door but the Halloween section is a little less obvious beside the Haddonfield sign of course. The white sign is from the "Ridgemont Federal Sanitarium" and the mail box is from the opening credits of the movie.
In all fairness, for being the write-off “selfie zone” of the year I’m liking these nice touches. Certainly an improvement over the bare signs of last year, and it’s leads me to believe they listened to the criticisms of AoH last year.
