So that's why he gets his own plaza.
As far as "Dallas/Americans have no sense of history", I told one of my more clever cow-orkers that I went to Dealy Plaza and wondered who Dealy was. She wondered what Dealy Plaza was. When I told her why it was famous, it seemed like news to her. I guess she's not much of a conspiracy buff.
