In a Tunisair from Tunis to Vienna, flying over a lighted city at night about 20 minutes before landing.
Me: "Is this Graz?" (Graz = Austria's 2nd largest city)
CC: "No, not grass, it's a city."
Reminds me of the story I heard about a couple who went on a motoring holiday in Europe. They wanted to visit Vienna on their travels. They came back and told their friends that they had a lovely time, but didn't manage to find Vienna with the limited maps etc that they had, and they never saw it signposted as they were driving through Austria.... but they did come across this beautiful city Wien, which almost made up for their disappointment !
