Lenski's concern about the plight of migrant laborers, which she had discovered while researching "Judy's Journey", led to her involvement with the Division of Home Missions of the National Council of Churches, which began to advocate and provide services for migrant workers and their children during the early 1950s. In 1952 she and Bulla wrote three plays about migrant families as a way of calling attention to the issue. In "The Bean Pickers", an African American mother and her two children followed the bean crops north along the east coast; "A Change of Heart" was about a Tejano family in Illinois; and "Strangers in a Strange Land" followed a displaced mining family from Kentucky to Arkansas for cotton-picking. The plays were distributed by the NCC for use by children.
