'let it not be forgot, there once was a spot, for one brief shining moment, called Camelot'

Dallas Mayor Mike Rawlings told those assembled that Kennedy's death ushered in a new generation.
"A new era dawned and another waned a half-century ago when hope and hatred collided right here in Dallas," he said. "Our collective hearts were broken."
The mayor unveiled a new addition to the monument at the plaza; the final words from the speech Kennedy was to give that day in Dallas:
We, in this country, in this generation, are by destiny rather than by choice the watchmen on the walls of world freedom. We ask, therefore, that we may be worthy of our power and responsibility, that we may exercise our strength with wisdom and restraint, and that we may achieve in our time and for all time the ancient vision of peace on earth, good will toward men. That must always be our goal, and the righteousness of our cause must always underlie our strength. For as was written long ago: except the Lord keep the city, the watchmen waketh but in vain.
