Where I used to live I had kids come by. The littlest ones around sundown, slightly older starting at around 7:30. By ten, it was all adults some not even bothering with a costume. By then I was locked up with the lights out. They would prowl around the back looking for a way in before they left. Had they come in, I would of course, shot them where they stood.
Last night I had no one come by. When I took the dog for a walk I did not see a single child, or anyone, in any kind of costume. I did see a maltese superman, a golden retriever fairy princess, a rottweiler fireman and the cutest little yorkie devil. Only dogs were dressed up, no people.
