There are a lot more “preppers” in Nevada County than you may think, says Brent Cassel, or he wouldn’t be in business.

“A lot of them are very secretive — they don’t want people to know what they have,” he said. “They don’t want people knocking on their door when things go bad. They’re collecting things like ammo, firearms, medical supplies, fire starters, food and water purification equipment. People are worried about where the world is at.”
