Everything Clark Griswold knows about exterior illumination he learnt from his Dad.
And everything you know about the magic of Christmas Lights hanging from houses, we want to know.
We're putting together our digital Christmas Lights map again this year, so you can check out the homes across Dubbo that are lit up like the Griswold's in National Lampoons Christmas Vacation.
Send us a photo of your entry so we can add it to the map this festive season.
And in the lasting words of CW Griswold Junior, Joy to the World.
