A backyard VBS is a Vacation Bible School conducted in the backyards of one or more homes. The major purpose is outreach and evangelism. By taking VBS away from the church to the neighborhood homes, a congregation is able to reach a greater number of unchurched homes and children.
Fliers advertising the event should be distributed in the neighborhood, and a poster should be placed on the front lawn of the home where the backyard VBS is being held. Children will spread the word to their friends.
