For all of us old enough to remember, the events of Sept. 11, 2001, will forever be etched in our minds and hearts. We recall where we were and what we were doing when we first heard that a plane collided into the North Tower of the World Trade Center. We may have thought it was an accident until a second plane hit the South Tower less than 20 minutes later. We watched in horror as the towers came down and people were running for their lives. The attack on the Pentagon and the crash of another plane in a rural Pennsylvania field made it clear to all that terrorists had declared war on us.
