Mrs The Millbrooker is in the shower; I've had a beer and have wasted lots of time surfing around on the interweb. I came across a travel quiz which has a map upon which you point and click in response to the names of cities or famous places that pop up.
If you've got a minute or two it's quite fun. The link is http://www.startfrom.co.uk/Start-Games/Brain/know-your-world.aspx
For the record my score was a total of 385,364; I got to level ten and my "travel IQ" is 113.
If you can beat that, I'll be impressed. It gets pretty damned hard after level eight.
