How does Janisse Ray use imagery in Ecology of a Cracker Childhood?

Example of Imagery:

"My homeland is about as ugly as a place gets. There's nothing in south Georgia, people will tell you, except straight, lonely roads, one-horse towns, sprawling farms, and tracts of planted pines. It's flat, monotonous, used-up, hotter than hell in summer and cold enough in winter that orange trees won't grow."
