Now go outside and look at the sky.
The Public Health Service Hospital in the Presidio is one of a very rare kind of buildings in San Francisco - an abandoned one.
The city is so densely populated that a large, publicly owned building will find a new use very soon - but not so in this case. The hospital has been closed for twenty years and only now are there finally plans on the horizon to create senior housing units in the building. We will see how many more years it will take for this vision to become a reality.
