Williams may be known for growing..But if you look at the map it's not exactly a metropolitan area. Their county has one of the highest concentration of medical card holders in the state (per capita). I don't think the cops have the time, money or desire to sift through exacty who is legal and who isn't ( Unless they are flying in the face of the law with a monster grow) There was a medical grower in the Medford area, who was being stupid about it and ended up getting busted…But he was growing 50+ plants and talking to the media about it. Seems that enforcement money is spent on the assholes who do giant grows in the forests and set traps for people who might be wandering by.
I've been growing up here for going on 25 years..I don't advertise that I grow, but it's a small town and I knew (they are both retired now) two local cops really well, they knew I was growing on my property and never bothered me about it.
