Tonight, our ward, the BYU-Idaho 60th ward of the BYU-Idaho First stake, had a ward activity where we went to a haunted house in Teton, ID. It's called 'The Haunted Mill' and has been in business for 11 years. It's pretty dang scary. You go up into the mill, and below it, and in a storage shed, and a bridge, and its all well done. The masks the actors use are professionally made masks like warthogs and aliens and creepers and everything. It was crazy.
It takes about 1.25 hours to go through it, so it's well worth the $5.
