There are countless stories to tell in San Francisco, but sometimes a picture says so much more that mere words. Each Tuesday we present to you 7 Reasons. (Our sister site LAist does the same thing, which we found too inspiring to resist.) Much like Photo du Jour highlighting a nifty image shot by our readers, 7 Reasons features recent photos from the SFist pool on Flickr showcasing the uniqueness of San Francisco. And with that, here are 7 reason why S.F. is, for lack of a better word, rad.

This week's 'Photo of the Week' winner: Troy Holden for his shot of birds swarming AT&T Park. (The winner can be seen as the lead cover image on SFist's Facebook page all week long.)
