Because I'm also an inveterate saver of computer files, I still have my carefully mapped-out itinerary for the trip, and thus can tell you with certainty that this story took place on Nov. 12, 2001.
The last military-industrial stop on my personal itinerary is off Route 44 in Taunton, Massachusetts where I pass near four buildings owned by General Dynamics in the Myles Standish Industrial Park.
