Invite young adults to turn the parish basement or another space into a spooky haunted house for Halloween. Advertise to children and parents at local schools and the children and grandchildren of parish members. Have face painting, games, and ghost storytelling for the kids, as well and an alternative trick or treating activity for little kids who might be too scared to go to the Haunted House portion. Offer a sugar-free alternative to diabetic children who can’t eat candy.
