Trunk or Treat carnivals or Harvest Carnivals have become the norm in my area during the halloween season. Many local churches will have members of the church line up cars with the trunk open in the church parking lot and hand out candy, usually the weekend before halloween or on the night of halloween. The cars are decorated with Biblical themes or non offensive secular themes. No occult or evil decorations are allowed.
Churches use this as an opportunity to build relationships with people in the community and provide a safer alternative to “trick or treating”.
Is that kind of thing done in local Catholic churches?
