I don't, to this day, know where the "Berkeley Marina" is. Is that the right name? If it is, I just googled it and I got a map and driving directions.
Not to mention the fact that flotsam and jetsam have been know to appear hundreds, even thousands of miles from their points of origin.
Doesn't seem like a big problem to me.
You have to know EXACTLY where he was fishing for the bodies to surface where they did.
