What is the setting of S. E. Hinton's Tex?

Heralded as her best novel, S. E. Hinton's
Tex is set in a small town in Oklahoma sometime during the late
1970s and early 1980s.  With a repression covering the country in the mid-1970s, many
farming communities were threatened economically.  In fact, record numbers of families
filed for bankruptcy during this period. Because of not having enough money, Tex's
brother Mason has sold both his horse and Tex's beloved horse Negrito, an act which
causes much contention between the brothers.

In Hinton's
novel, also, Jamie, the girlfriend of Tex, speaks often of "Women's Lib," a movement
begun in the 1970s as women fought gender discrimination in the workplace. 
Organizations fought for the Equal Rights Amendment (ERA), and they fought against
sexual harrassment on the job site.  When Tex wants to go too far with Jamie, she
refuses because she, like Mason, wants to leave the small town and make a better future
for herself.  Such thinking is reflective of this Women's Rights movement of the
setting.
