I've been driving around looking, and I've seen a lot of people scale back, but a lot of people doing something when they haven't before as well. I'm not talking full yard haunts or anything, but hey, they suddenly have a few decorations on the doors/windows. cool!
I don't do 'competitions' or anything for any holiday, but we have a really fun game going with one of our neighbors. They are THE CHRISTMAS HOUSE of the neighborhood, much like we are the Halloween house.
For the last five years, they set their lights up in October. They normally don't light them till thanksgiving, but they are sure putting them up and testing them in October.
The great thing, though is they just RUN WITH IT for Halloween.
Full winter wonderland setup in the yard, lights on, Christmas music going. Answer the door as santa/mrs clause. Hand out candy canes.
Towards the end of the night, they'll come over to our place Christmas caroling as the full house of santa and the elves.
Meanwhile, we leave our Halloween decorations out, wrap them in Christmas lights, and have begun to go trick or treat at their house Christmas eve.
