Osterland said that his family also enjoys dressing up as the Griswolds. This year, his 3-year-old son Lucas had a blast channeling Cousin Eddie and in March, a new baby girl will join the party.

\"We'll have one boy, one girl -- just like the Griswolds...let's just say [the name] Audrey was put on the table and vetoed,\" Osterland joked.

The interior of Osterland's home is decorated in handmade props that mimic scenes from \"Christmas Vacation\" including Aunt Bethany's Jello mold, an oversized tree, a faux squirrel and more.

Stringing the lights onto all 360 degrees of the house takes weeks. The Osterlands start in October with family, friends and neighbors all lending a hand.
