My late wife and I and a friend did the most effective spook house trick-or-treat set-up. We just set up a scary atmosphere by the front door, got into scary costumes, and mostly stayed quiet. The kids would come in smart-assed, and by the time they took the candy, they ran screaming, and we did almost nothing. In their minds, they were ready to be terrified, and they were. My late wife was a Halloween person. And so is my wife now. Another year.
