When I think of Halloween, I think of kids outside in the dark. Traditionally, this is the way it works. First, darkness makes everything just a little bit spookier and more Halloween-like. Second, the end of October used to be after the end of Daylight Savings Time such that it would get dark earlier. Of course this year, Daylight Savings Time doesn't end until November 4. However, let's assume it's dark. Kids running around in the dark on streets with cars can lead to bad things.
