One thing I like about how we've done things, we don't make it a candy run. They only do our park which we know everyone, one of the local businesses that does a fun house (can't call it haunted, they keep it in line for the little ones) and the police station.
Oh, and our park is starting to be older parents and grandparents so they are at the stage where they really enjoy seeing the kids in costume so it's a double win
