When I was a kid, we would drive by a place in the middle of town almost, that looked like a huge swamp, with little short derricks all over. My father said it was a salt mine. I was skeptical, but never dared question. There was no internet back then, so now I'm wondering if it was true, or was he pulling my leg. There is no picture of that place. Salt deposits across the U.S., so it's possible. NE Ohio is covered. I could not find any picture that looked even close to what I remember. Modern salt mine in Detroit is the closest. Old picture of elaborate bamboo pipelines sending natural gas to operate salt mines in China. Does anyone remember salt mines?
