A new idea for a cover for Prime Base

[cosmicfish]

I am inclined to say that a grain elevator is probably not a good cover. First, the areas that have grain elevators are also areas that have a not-inconsiderable population. Second, these locations are probably going to be suspicious if they fall out of use without replacement. Third, you cannot disguise nearly enough stuff as grain.

I think an old mine or other such venture are probably a lot more desirable - no/minimal nearby population, easy explanation for a decade or two of heavy activity followed by abandonment, lots of use for a variety of heavy equipment.
