I also open the bin containing my original journals to find the red journal, the journal dated May through August 1980. Upon finding the entry on the day that I visited the Kingdom hall for the first time, I find it was on Sunday, 29 June 1980 which entry has the header of Big River. I go to my map and find that the Big River is just south of Mendocino, California and drive there.
