"You gotta get the mine first. Then when you get the mine, you get the salt. Then when you get the salt, then you get the elevated blood pressure."
2000 feet underneath Lake Erie (because evil loves its puns), the Ohio mine stretches out for three miles. The only way to get to this portal to a salty hell is with a four-minute elevator ride, a series of airlocks and sudden primal fears of Stygian abodes. Fresh air has to be pumped down to the miners, who are also required to carry an hour's worth of emergency oxygen. Not that that's going to do them much good when they dig too deep and awaken a giant hungry dragon.
"All the ingredients for jerky. Nice."
That all feels like a lot of hassle for salt. Even their equipment makes it look like they're burrowing through an ancient alien installation in search of advanced technology, rather than in search of french fry seasoning.
