Unless a neighbor’s grandchild comes to your door, you should not get any trick-or-treaters.
In the 10 years we have lived here, we have had no goblins at the door. We go to our grandkids’ home to see them.
“Soliciting” is not allowed and hope that we never see carloads arriving in the neighborhood. As much as that sounds like we are the Halloween Grinch, it would be a nightmare for us.
