Since the Gordon family has a website for their light show, I thought I'd share it with you.
They are on Quincy, near Ohio, on the north side of the street. As you approach their home, tune to 97.5 FM and you will hear the music that coordinates with their light show.
Here are their website: http://www.gordonlights.com/
You do want to hear the accompanying music.
And you will want to honor their request to not park directly in front of the home to avoid obstructing the show.
