What about the 'ship' (can't remember if it was in a bottle) which David has? I think it's mentioned as a former, current, or shall-be type ship.
So funny; I saw this thread while watching Sam, Dean, ((Rufus)), Bobby and Grandpa Mitch Pileggi on Supernatural. (This was at the cannery!)
By 1968ish, how much 'fishing' was done by a few 'boats', wasn't most done on a large scale? (Which, of course, within less than 20 years, would lead into the 'catching dolphins while fishing with large nets.)
