I live on a dead end unpaved road. The homes are 500 feet apart, and in addition, my driveway is over 400 feet long. There is no outdoor lighting. And, on this road, there are no families with kids. In 22 years, I have never seen a Trick or Treater.
So, I buy no candy. But I have a small stash of $1 coins to give out if a kid ever shows up.
