Believing batshit crazy things isn't unique to rural areas. In fact, I'd say it's more common in cities simply because there are more people there.
I know a woman who lives in Chicago who doesn't believe in dinosaurs. It's not a religious thing, it's just that dinosaurs don't fit into her mindset somehow.
I dated a woman in New York (native New Yorker) whose entire family believed that the moon landings were fake.
I know a guy in Houston who believes that drinking his own pee is helping him live longer.
Crazy is everywhere. It obeys no geographic, social, wealth, or political boundaries.
