In the 1964 movie "Fail-Safe," there is scene where an American Air Force officer is talking via hot-line with a Soviet air defense official.
The nukes are about to hit the fan. Both know it is too late to avert it.
They discover that both had spent time in London during World War II. Both say they loved it there.
The Soviet official offers the opinion that great cities, such as London, are the ones where you can walk and walk and make unexpected discoveries and encounter history at seemingly every turn.
Do you agree? And if so, what cities with which you are familiar have that characteristic?
