How do you get a cannabis club card in SF or Oakland, CA?

I had a card in SF, ca that expired in Sept of last year (05) and was told it was better to get a card in Oakland, ca. But now i can't seem to find any ads in the advertiser which is where i got the doctors address last time. can anyone give me a address of a doctor that's not to strick to get a new card?

the last doctor all i said was i had a bad back ( which I do ) but i did'nt have to show any documentation or anything.. it was pretty much in and out.. So if anyone knows a layed back doctor that i can get re-newed I'd really appreciate it..
