greetings san francisco,

i was wondering if there's anywhere in the city where i would be able to borrow a bike from? i realize this might be ridiculous, but i talked to this girl a couple weeks ago or so (her name was kat, is she on this board?) and she recommended me some shop that lets you borrow bikes if you put down a deposit or something? however, i have since disregarded her information because i was planning on bringing my beater up and just riding that. i pull out the beater yesterday to ride it around/get used to it, and i discover it has a bent fork and is currently unridable. this puts me in a bit of a bind.

i'll be there friday late-afternoon through monday morning. if anybody knows of anything that would help me out in this situation, please let me know. thank you!
