Imperial Irrigation District, I certainly enjoyed your 90 years edition in the Imperial Valley Press.
As a teacher in the El Centro Elementary School District, the Imperial Irrigation District provided information to many of my students over the years during their third- or fourth-grade field trips to the dam. The students were fascinated with what they saw at the dam and how the crops were irrigated. (Of course those were the good old days when the individual classes could afford field trips without selling candy, etc.)
Dippy Duck was loved by all, the coloring books, pencils, pins, stickers, the film. Donna Hampton made sure we teachers got the goodies for the students who happened to be absent that day.
After field trips and special presentations, writing letters made a natural learning experience for the students not only in language arts — letter writing and letter form — but also penmanship.
