There are several other YouTube videos that feature San Nicholas itself, and a trio called El Trio San Nicholas Hidalgo. Enjoy.
Between 1963 and 1970, the Conference on Inter American Projects sent university students to dozens of projects located in the Sierra Oriental of Mexico. Canadian sites were situated in Hidalgo State in the heart of the Huasteca. Most students lived in the smaller ranchos on the outskirts of the Municipios of Pisaflores, Tianguistengo, Xochicoatlan, Molango and San Nicolas de Jacala. This site is maintained by volunteers in those projects, and whose lives were enriched by the experience.
