I remember Mac saying that the Cumberford and Mott both went underground as they were afraid the GM might take some nasty retribution if they were found. In what must have been 1999 I brought up the Ford banner in the reflecting pool story to Chuck Jordan. I was thinking it was a clever prank (maybe not in good conservative corporate taste). At this point Chuck was well retired and way more than 30 years after the event; he still no humor in their prank. Maybe the inquisition that went with GM trying to find out the culprit(s) left deep scars.
