The opposite of Mountain would be Valley... I work in one, as I said, I live on the top of a mountian (more of a hill, but we call it a mountain). What do I think of when I think of the opposite of mountain? I think of the school where I work at, being made to feel like an incompetent shit by white trash every day and trying to find some way to like them so that I can face going to work every day.
