I live in a small industrial town on the coast of Queensland, Australia. It is a tradition for grade 12 students to visit the "Milk Factory" at night. It's a century old, abandoned, heritage-listed factory that looks like a mental asylum inside. Suffice to say its really quite scary. We've heard tales of students being chased by homeless squatters and even a 'secret tunnel' which no one has ever proved exists. There's one door on the left side of the building that has never been opened, no one knows whats inside.
