Since you can't really see it all allow me to explain. nearly every square inch of the house and front yard was covered in lights. There are two signs that tell you to tune your radios to FM 90.7, and when you do that is when the magic kicks in. They are broadcasting Christmas music and the lights turn on and off, flash, fade in and out, etc. to the music. It was pretty cool and the kids loved it. Needless to say there were 8-10 other cars doing the same thing we were and many of them got out of their cars to enjoy it. Here is the full effect.
Needless to say we had and fun finding it, the kids enjoyed it, and we will probably visit it again on Christmas eve.
