82-year-old goes ‘Back to School’ with his college freshman granddaughter

Rodney Dangerfield may have played a successful businessman who went back to college with his chagrined son in the 1986 movie, “Back to School,” but Rene Neira, 82, is in college for real, and his granddaughter and fellow student is thrilled about it.

Melanie Salazar, 18, and her grandfather are both enrolled at Palo Alto College, in San Antonio, Texas. She is a freshman, just starting her liberal arts education, while Neira is taking the last class he needs for an associate’s degree in economics.
