While visiting DC last October, I found that a makeshift fence had been built around the Washington Monument, presumably as some sort of interim measure to prevent possible terrorist attack. I was struck by the how changed a nation we had become since 9/11 and wanted to use the fence/chain as symbolic of that change. Being able to juxtiposition the chain against the Washington Monument was easy enough. But the position of the sun was brutal. So I inched downward ever so slightly until one of the links in the chain blocked the majority of the sun's direct rays. And this helped to make for an acceptable shot.
