A pathetic attempt at telling the Grail story, in particular, the North American angle. the storyline lost all credibility beyond your visit to Rosslyn Castle. Despite pointing out the Sinclair connection, the remainder of your conjecture was like grasping at straws.
A more accurate portrayal would have highlighted Sinclair's voyage to America in 1398, almost 100 years before Columbus, Nova Scotia's Oak Island, Rhode Island's Newport Tower and the founding of Montreal. Better luck next time, you flunked this histroy lesson...or possibly made it up on the flight over during taping of the episode.
