Dedication

Cinco, a formidable man with a strong character, dedicated many years of his life to working on the Rowland Rancho before retiring. His contributions extended beyond the ranch, as he also worked in the hay industry and with the Rowland water district. Cinco played a pivotal role in managing the Rowland Rancho LLC and maintained close relationships with all the businessmen on the property. Beyond his professional achievements, Cinco had a deep appreciation and love for the ocean. The photograph above captures him emerging from the ocean after spearfishing, having caught his dinner.
