Church members and friends decorate trunks and truck beds. Costumed characters hand out treats and smiles. This year there will be games and prizes to share as well. Trunk-or-Treat is open during the trick or treat hours for Monticello, October 31st, 4:00 p.m.-7:00 p.m. Trunk-or-Treat is located in the parking lot of Zwingli United Church of Christ at 416 E. Lake Ave., Monticello. As with all Zwingli events, everyone is welcome and encouraged to come!
