To the original poster:
I have been to rehab. Unless I'd have been ready, it wouldn't have made a difference what type of treatment center I attended. I happened to attend a pretty bare bones university facility, we had all kinds of drug addicts and alcoholics mixed in there. Some of us were there to work, others were there to get by. A farm wouldn't have changed that fact.
In my experience it was my willingness to take the program seriously that has kept me sober so far. I am willing to use the tools I was given. The setting didn't matter so much, it was that I'd hit my personal rock bottom, and truly desired to be a better person.
