We had over 500. My street really gets into Halloween. We have one neighbor who decorates for Christmas in October and his costume is Cousin Eddie from Christmas Vacation, Two other neighbors combine efforts and build a Haunted House in the driveway. Neighbor across the way had a Monsters Inc dance party in his Mike costume. Next door was Zombie Carnival with a PVC ferris wheel with zombie dolls, a ring master, bearded lady and fortune teller. Our house for the last few years has been a full graveyard and our version of Haunted Mansion.
