But are the people really not at home? I heard this experience about one JW who was knocking on the doors in a neighborhood. After 1 hr of writing down "Not at Homes" on a slip of paper, a car alarm in the neighborhood went off. Then, to his surprise, everyone that was marked down as not home, looked out of their doors to investigate if it was their car alarm. When he saw that, he just crumpled the paper, threw it away, and considered that everyone was home and the Territory was worked.
The RVs are home. They just are playing Hide and Seek.
