please, help me to understand the meaning of the sentence "eating local means shoot your own squirrels." Speaker is from Arkansas. Are there any similar sayings?
Here's the context:
“The Fiveashes have lived in Toad Suck for as long as anyone can remember,” Priscilla said. “They work hard, go to church, and send their kids to school. They shop at Dollar Tree because they don’t want to get dressed up for Walmart. They think eating local means shoot your own squirrels. And when my kin start talking, you’ll wish they came with subtitles.
