Yes,
I estimate that Farren was in San Francisco for at least six months. It could have been more time. Much more time. Also concerning his travels, I think that he left in August of 1979. We know that he called his family often to make sure that he was safe.
I wonder if Farren ever came home for like Thanksgiving of 1979 or Christmas of 1979 to visit? It seemed that the main friction was between his Mother and he, probably not his Aunt and Uncle. I always would have wanted to ask Farren, what places did he want to see, or actually see on his journeys, and the people whom he met and befriended along the way!
I can't remember now if his Aunt and Uncle are still living. His grandmother passed not to long ago. And I know that the family committed to keeping the same phone number all these years, just in case Farren tried to call.
I think Farren was frightened of LE coming after him for not being able to pay his bills, and I think he took his own life by going down to the San Francisco Bay bridge late at night, and jumped.
He probably told friends and acquaintances at the hotel that he wanted to continue his travels. But I agree with
@Ciriii57. If Farren was living with other people at the hotel, why would the bill pay reside with him? And I also agree that as "friends." why wouldn't they call the police after Farren had left for a long time, and not come back? Or were these "friends" also living a transit lifestyle where they moved from place to place and did not settle down for long periods of time. But I think Farren did settle down in San Francisco. It's seems that Farren did very well for himself for about nine months.
