On a weekend break a short while ago I saw this market cross.
On the side perhaps you can see that it has a plaque with distances
to local and more distant towns:
Where was I?
What is the minimum amount of information you need to know where I
was? Is some of the information redundant?
Is some of the information more useful than other parts?
How accurate can you be about exactly where I was from the
distances that are given?
Then why not think about the following questions:
Why has someone bothered to include so much information?
What can you find out about this place?
Can you make up similar problems of your own?
