Now go outside and look at the sky.
Hill 88 is an abandoned Nike missile control center high up in the Marin Headlands near San Francisco.
I'm a regular visitor of this place on my hikes across from the ocean to the bay, and on a recent visit the place was shrouded in fog. It was a cold and drizzly Sunday and I had the place all to myself, only adding to the desolation.
There is always something special about visiting abandoned sites like this - filled with the ghosts of a past that is visibly slipping away, a steady reminder that nothing of our physical presence, not even concrete and steel, will survive for more than a few generations.
And I'm certainly not alone with this fascination for crumbly concrete - there are hundreds of well-photographed sites out there about abandonded and forbidden places. Check out Infiltration.org for many links to urban exploration...
