My son helped me decorate for Halloween this year. He also answered the door every single ring. Of course, he did it by running up to the door and slamming into it and acting like a monster. He scared some of the little kids really good. One kid was shaking so bad he could hardly hold onto his candy sack.
The older kids (8 and up) loved it though.
The signs were my son's idea.
It was scarier at night with the lights and all. Plus we have this skeleton head that is motion activated. It wiggles it's eyes and makes this aweful noise. We have it on the porch where people don't really notice it until it scares the crap out of them. MWAAHAA
