the most memorable thing you've ever seen or done?
Mine is the 1999 solar eclipse on the Isles of Scilly. It was awesome in the old fashioned sense of the word. I was gob-smacked.
Standing on the spot where JFK was shot .
JFK was shot from a moving car so according to Newton there is no point in space at which he was shot; only a point in time.
So why is there a big metal cross marked on the ground. Ok I looked out of the window in the book depository he was supposedly shot from.
Fair enough. The cross can only mark the area he was in when he was shot.
