I'd speculate that a good place for growing mj on federal property would be as far as possible from places that are popular with backpackers or anybody else. Perhaps clear-cuts might be good, especially given desirability of sunlight.

I spent a few days with a guy who claimed to have previously worked as a guard for an mj grower in northern Calif in the late 1980s. My impression is, that the site was at a relatively low elevation. I don't know who owned the property.

According to him, he was hired in part due to his ability and willingness to use a firearm in the line of duty. He claimed there was a conflict with local indians & had various other stories that were perhaps unbelievable and somewhat entertaining.
