On the day that I took an early flight from Boston to Chicago, my later-departing colleagues never made it to the Windy City. Tiles on the ceiling of the Ted Williams tunnel crashed down and Logan Airport access from the city was held up for hours. No problem. I had the day to myself. A dinner at the bar at Topolobambo. A classical music concert in a beautiful church. Oh, and a brief stop here at the Nokia store to see their display of Bose headphones, the purpose of our planned visit.
