When I began taking photos of abandoned locations eight years ago, I always assumed there'd be a return visit to these sites and my friends and I would always talk about "the next time." But over the years, I have learned that each visit should be treated as the last because these relics can wind up inaccessible or demolished very quickly.
This photo was taken during my first visit to a beautiful glass building, a machine shop, at the former Hunter's Point Naval Shipyard in San Francisco back in 2006. I made a few visits over the next two years, but when the site became much more difficult to access, I never made it back to this building.
