Just for a moment, pretend all the Halloween events that we typically know in LA do cancel (which is actually not all that unlikely). Given the demand and dedication to Halloween/Haunt events in LA, it is not going to be the death knell of haunts for SoCal
First of all, the dedication to Halloween in SoCal is intense and huge. Midsummer Scream just keeps expanding, and would've been 3 days long this year. There's an audience very hungry for this--doesn't LA have more haunts/haunt experiences than anywhere else?--that will always return.
Second, many of those haunts will evolve to more online/socially distant experiences. I was late to the party, but I did the Arcana/Jadesintown Instagram, and it was pretty fun (you still can do it... just search for the IG account Jadesintown and start from the beginning). I also just did the first trial run of Road Trip Mysteries: Simi Knolls, and it was fun as well.
Were they as good as HHN? Of course not, but they still offered creepiness in safe ways. I don't think HHN would be able to pull that off. KSF? Maybe. Knott's has been especially clever during this shut down with their IG account having stories of Sad Eye Joe visiting and commenting on different places in the park. Knott's doesn't mind taking risks and trying new things (remember Trapped, that haunt show in the Mystery Lodge Theater, virtual experiences, and the shooter mazes?), so while unlikely, I'm not taking them out of the equation just yet of coming up with something else should they cancel.
But mainly, think of all the independent events: CreepLA, Zombie Joe Underground, Sinister Pointe, Dark Harbor (yes, I know they did cancel for this year), Delusion, Boney Island, and the myriad of home haunts in Los Angeles. I would bet a good many of them are going to evolve and find new ways to scare.
Sure, while I'd rather have a more traditional haunt, in a way, it's kind of exciting to see what some of these very talents independent people will come up with. CreepLA has the best reputation of reinventing themselves and trying new things, so I'm hoping they'll come up with something. And ZJU was already streaming online shows. Also, maybe "alone" mazes will find a way to make a comeback. We have some of the best and cleverest effects, desgin, and creative people in the world, and sometimes restrictions and obstacles can result in new and more creative ideas to emerge. I think they'll find other ways to keep the spirit alive.
