This was way back 2 years ago. The guy is an electrical engineer and spent like more than $10K for this X'mas lights and sound.
The story behind this is that he will take it down when traffic thru his neighborhood will be disrupted due to people admiring his decors. And sure enough, a lot of cars are lining up to watch and admire his decors each night that his neighbors complained -plus an accident (fender bender) happened. He then shut down his decors. I guess to avoid lawsuits from neighbors.
