The Cross Country Night category also includes some additional shots of San Francisco. When I first visited this site a few years ago, the first San Francisco night photograph that I found was a shot of the coffee shop where fellow night photographer Mike Quinn had a permanent installation of his night photographs (strangely enough, I can't find that photograph on this website, anymore). Gedney considered calling his night series "The Single Future of the Night". The Duke university website also includes a lot of Gedney's personal writings.
Thanks to Consientious, once again, for reminding me about Gedney's website.
