Can you guess?

When we were traveling through the Middle East and Central Asia we learned to refer to anything of value by a code name.

Being over heard to say you needed to catch up with 'Charlie' (our code name for the bank) was much safer than saying that you needed to go to the bank and cash a travelers cheque, for example and it's a custom we have continued. In this regard we have code named our new journey 'Operation Canterbury'.

So what is Operation Canterbury? Is it:

a/ a brand of sports clothing?

b/ a series of short stories by Geoffrey Chaucer?

c/ a town in England?

d/ all or none of the above,

and how does it relate to the first steps I took last week?

Can you guess?
