I always answer that question "Southampton"
Here in Austria, I usually get a frown, or a "where", so I follow-up with "Where the Titanitc sailed from"
However, on two occasions I got answers that shocked me.
The first was the grandmother of my wife (rest in peace). She was about 85 at the time, and she immeidately started going on about listening to WW2 on Nazi radio, and Southampton was the first place she remembers being reported to have been attacked during the Blitz on the radio, the Supermarine factory in Woolston.
The other was last summer, from a bloke nearing retirement, who immediately answered "you had a good football team in the 80s", which made me rather sad...
