The elementary school at La Tinaja — Escuela Primaria 18 de Marzo — is named after one of the most famous dates in Mexico history. On March 18, 1938, President Lazaro Cardenas nationalized the country’s oil industry, kicking out foreign-owned companies.
Principal Socorro Lara has been at the school 15 years and in the Ocampo municipality 35. She doubles as a teacher. In the mornings, she substitutes, and in the evenings, she teaches kids who are struggling.
There are a total of about 50 schools in Ocampo, and this is the best, municipality education official Jose Juan Salazar says.
