Uhm I would be shocked to see them use Fire in the haunts. It may be something in the fire code more then likely. Fire is not good in confined spaces.
They just used fire last year in the Orfanage house.
My theory has always been your first year is your favorite. 12 was to me one of the worst I was not happy with the change to IOA it was way to small. 13 was just blah houses except all night drive in I like 14 because it was the last year of the parade.
That is because 18 and 19 were lackluster. 20 was a good year. HHN has changed so much from the first years and has changed a lot since I started going. Some change good some change not. But you have to change.
But you can't say that "My theory has always been your first year is your favorite" and then apply exceptions based on your opinion, and your opinion alone.
For the record, my first year was 12, but my favorite was 18.
People may apply the favorite to a year not based solely on locations, haunts, and scare; they may factor in random moments/memories and people they were with.
It will always be based on the best expirence you had on any given year, Short lines, great service, or even the weather...
