The family names on the Highway 101 packing sheds belong to immigrants who first milked cows. Ticinese Swiss-Italians and Azorean Portuguese rented land from the 1880s, building a dairy herd of more than twenty-five thousand cows by 1924 before the postwar collapse pushed alfalfa ground into vegetables. The episode also tests the folk belief that Swiss-Italians married into land-grant families, finding they got ground by working, renting, and buying.
The dairy herd's size and timing vary by source, with the 1925 soil survey weighted most. Accounts conflict over the month Monroe was crowned, and some wrongly call Molera an Italian immigrant when he was California-born.
