forget about finding co-ops. it's not like california -- there are no cannabis clubs that will sell you marijuana in a store like in oakland.

your best bet is to grow your own weed after you get your medical papers, or find a very reliable drug dealer who you don't absolutely hate (and it can be VERY HARD sometimes to find a good drug dealer)..

oh and if you go to portland, don't buy your weed at the waterfront park, whatever you do!!!!!!!!!!!
