Working "underground" . . . .

[Donovan]

I've been to the salt mine in Hutchinson Kansas a number of times and it's creepy as hell but not exactly claustrophobic. In a weird way, because those mines stretch on for miles, it's like being lost in a maze. Everything looks the same. No natural landmarks. When the light fails or is turned off, there is no ambient light of any kind, it is pitch black. No cell reception at all, you are about a thousand feet below ground, probably have wi/fi and cable problems too. The temperature is constant and there is zero moisture because the salt sucks it all up, so your stuff lasts forever. No bugs, no growing things, no mold, no nature sounds, nothing. Just a very alien environment. Only one or two routes in or out, each involving major elevator equipment so if catastrophe struck you're screwed. The ride to the surface takes a few minutes. And is controlled by an operator either down below or on the surface.

No way in hell I'd work in a mine.
