The practice involves decorating the trunks of vehicles, typically in a parking lot, to create themed displays. Participants, often children in costume, proceed from vehicle to vehicle, collecting candy and other treats. This provides a contained, community-oriented alternative to traditional door-to-door trick-or-treating.
This activity fosters community engagement, offering a safe and controlled environment for families during the Halloween season. Its popularity has grown due to its accessibility, allowing individuals to participate regardless of residential access to traditional trick-or-treating locations. The origins of such events stem from a desire to provide secure and inclusive holiday experiences.
