10th Street, South of Market, San Francisco. On my way from work up to the Civic Center BART station — a change of pace from 16th and Mission BART. I just liked the door color. And the rest of the palette, too. If you’re not a habitue of the city, this part of San Francisco was once filled with warehouses and light industry. Some still remains, but large tracts have long since been cleared and redeveloped into parks, hotels, condos, retail centers, and the like. This part of the South of Market neighborhood, well west of downtown, has changed more slowly and there’s still plenty of evidence of what used to be.
