I'm personally a little bit doubtful we'll see the hanging this year, both due to the ending of last year's show and the fact that its a particularly hard show to distance people for since people tend to just stand in a big clump once the benches are full, although given how many crazy things have happened this year I have no doubt they'd have plenty of things to reference.
On the topic of lore based mazes, I am 100% in favor, though I'm not really sure what kind of thing they could do in ghost town that isn't more Sarah Marshall, but I still really like that knotts has been doing a few mazes that tie into the theme of the adjacent scare zone (Origins for Ghost Town, Pumpkin Eater for The Hollow, Dark Ride for CarnEvil). I can't really think of what else they could do with that unless they find some space to bring back the Gunslinger location and do a Forsaken Lake based maze.
Also, does anyone else find it strange that the Waxworks facade is seemingly missing based on the footage we have? I feel like in the past when it was trick or treat the facade stayed up between years, as most mazes do. Do you think we just havent gotten a good angle of it or its being retouched, or could Waxworks have been a one and done theme?
