My sister-in-law says that there is an Easter version as well. Glad I'm not here for that.
Most of the houses are relatively decent in their decorations. A wreath on every window, a Santa on the roof. The public decorations are prolific, but non-religious: wreaths, snowmen, red bows, glitter, tinsel, flashing lights, trees.
There is a big fight about a nativity scene being held on public property. Since there is separation of church and state, there can be no religious matter on public grounds. But the Knights of Columbus have a special dispensation, that if they pay rent for the property, pay for the scene themselves, and have guards on duty 24/7, then they can have a nativity scene set up.
The prize in the department I-Don't-Want-Your-Electricity-Bill is:
The whole entire house is draped in lights. Blinking lights. Colored lights. There are creatures on the lawn. They blink. I would not want to have to live next to this.
