I was reading a blog entry on the first moon walk. The author included this line:
Some people say that September 11, 2001 was the moment America best defined itself. I respectfully disagree. On the evening of July 20, 1969 we defined ourselves not by our fear of what could happen, but our dreams of what would happen, if we only dared to dream.
That is one of the best things I have read in a very long time.
