San Francisco Rust

I was in San Francisco recently on business and I challenged myself to get out and shoot as much as I could with the free time that I had. While shooting the well-known sites, such as the Golden Gate Bridge, were cool, I think I had more fun exploring things that were right under my nose - like the rusted links found in this picture. These links act as a guard rail so people don't fall into the bay below. The cracked and rusted metal caught my attention, which I thought would make an interesting subject for my macro lens.
