It must be that time of the year. Lock your doors, dim the lights. If this photograph is anything to go by, mishief is likely to be unleased soon on Formby.......whoooh.
If you've ever wondered where this event began try Wikipedia:
Halloween (or Hallowe'en) is an annual holiday observed on October 31, which commonly includes activities such as trick-or-treating, attending costume parties, carving jack-o'-lanterns, bonfires, apple bobbing, visiting haunted attractions, playing pranks, telling scary stories, and watching horror films....
Some prefer to remember it as the night before All Hallows Day.
