Years ago, Dealey Plaza conspiracy man Robert Groden reportedly strolled into the center lane of Elm Street and taped down a white "X" to mark the spot where President John F. Kennedy was struck with the fatal bullet on November 22, 1963...

No longer. On Monday afternoon, as the city prepared Dealey Plaza for Friday's official JFK commemoration, workers removed the "X."

"We are laying asphalt to level out the streets and remove any trip hazards," city spokesman Frank Librio told The Dallas Morning News' Scott Goldstein. "With thousands visiting the area this week, we think that is prudent."
