Today is the 16th anniversary of the Sept. 11, 2001 terrorist attacks in New York and Washington, D.C. Many of you, like me, will remember exactly where you were when you learned about the seminal event that ushered in the "War on Terror." In my case, I was in Barre, Vermont, overseeing the renovation of an 1891 school into a history center. A construction worker, listening to the local NPR radio station, delivered the news of the first plane hitting the World Trade Center. Upon hearing about the first strike, all of us assumed it was a ghastly pilot error. Shortly afterward, we learned about the second plane. Our world changed.
