Over the years, it's been a tradition to mesh metal with xmas light displays on the casa. Let me rephrase that... It has been a tradition for other, more holiday inclined people to mesh metal with xmas light displays on their own homes. I don't decorate - Guy Code -  But this guy goes out every year to bring the best of metal to neighborhood, and his neighbors both enjoy and hate him for it. This years Slayer display seems a little plain to the stuff he's done in the past, but at least he's continuing the tradition.
