As the title says: 51 things you can’t see on Google Maps, via Bruce Schneier. No prizes for guessing that most of them are military installations or government-sponsored institutions.

In a decade’s time, will there be more things on this list, or less? Will the list vary according to which nation-state you make your search from? Will there be a ‘black’ maps service that unfuzzes the obscured areas, if you know how to find it (and if there isn’t already)?
