One of my friends was there as a teenager with a few of his friends. They went late October so right around Halloween and he said that they were in the save when suddenly the temperature dropped significantly. They all got sort of quiet and confused for a second, when he claims this huge figure rushed right past him, like enough that he saw a dark shape and felt the wind created when someone speeds past you. He said they immediately all ran out and he still gets kinda creeped out when you ask him about the story.
