Covered in lights and armed with a fog machine, Gary Pelletier stands outside his Nashua home waiting for trick-or-treaters on Halloween. For the past 10 years, Pelletier has adorned in lights powered by extension cords while handing out candy. The idea came when his friends wanted to dress up, however, he wanted to outdo everyone and it has stuck every year since. "Some little kids are scared, some are fascinated," Pelletier said. "It's something they've never seen before."
