Halloween decorations in my neighbourhood tend to follow the popular trends. One year, the area was besieged by witches flying into trees. Another year, smiling scarecrows had taken over. Then there was the year that the front of at least one house on every street was obscured by a giant inflatable. But it has been a long time since the heyday of tree ghosts.
I believe the occupants of this house just moved in this year. Good to see they're ghost-friendly people.
