I never participated in toilet papering yards, although it was done from time to time. Later, when I was in my late 20s or early 30s, it became popular to fill a person's lawn with plastic forks stuck into the dirt. People my age were doing it! And I know of one young adult woman who sneaked into a neighbor's yard at night to steal all the plastic pink flamingos because she thought they were ugly. Or did she bring more to add to the unsightly flock? Oh dear, it was too long ago, and I'm not sure!
