There's a link at the end of this article.
They're by Trey Ratcliff, who almost shares a surname with me, and they cover a mixture of San Francisco scenes plus visits to tech companies in the region. The shot of "Alcatraz in the Dusk" (on page 3 of the San Francisco collection) is one of my favourites but I've chosen a classic view of the Golden Gate bridge to illustrate this article. Scoll down the page of Trey's shots and blog articles to see some wonderful work - including the Alcatraz shot.

Nice shots of London, my home city, too: http://www.stuckincustoms.com/category/travel/uk/london/
