I always refer to San Francisco as the greatest urban center west of Chicago, or the prettiest city west of Chicago. It's been somewhere Ive visited at least once a year since I was young, and twice a year the last 4 years.
I thought it would be nice to have another SF thread in the My City Photos SSP section. I won't be able to post to it constantly like I do my Downtown Los Angeles Thread, but I will be sure to update it each time I visit.
