I think where BL is found will be determined largely by his frame of mind, and grounding in reality. If his mental state has deteriorated markedly, he will likely be hunkered down in the woods, running like a scared animal. (I think he's secreted away in a remote cabin, as posted upthread).
However, it's just as likely that he will be hiding in plain site. Grow the hair and neatly cut/dye it, add a mustache and plano glasses to hide those notable drooping eyes, put him in slacks and a blazer, and I could talk directly to him and not register that it was him. Our minds contextualize people. That's why we struggle to recognize people when they are outside the surroundings we normally see them, or are dressed very different.
What I'm counting on betraying him, in his behavior. Even tho we've seen BL acting all chummy with LE in that now infamous Moab video, it's questionable whether he could pull that off for any period of time. So, if he is existing in plain site, I speculate it's his behavior that will lead to his arrest.
