Mary really would be the best icon for this year. I was fortunate enough to go to 18 and the story and website was the best. Never felt more immersed because of all of the Easter eggs and references throughout the park. Anyway, Mary was all about two things: Fear and the past. To take us back through the mirror to look at our past would fit perfect for an anniversary year. Candy man would also make a lot of sense as he basically is a variation of Bloody Mary. Keough is for Francis Patrick Keough, he was the archbishop Of Baltimore that used the motto and crest. Not sure if there is any significance.
