Just to make things clear, my wife's grasp of geography is only slightly poorer than her knowledge of particle physics as is applied to the chaos theory. Obviously then, any guesses are likely to be somewhat awry of the truth.
However, I must be fair here. Most of us, when faced with a question to which the answer is a mystery, most of us will say something like, "pffff - I dunno." Such a mundane response is not for Julie. No, she'll take a stab in the dark - with a corkscrew, usually.

*and yes, I'm fully aware that Jean-Luc still would have been wildly inaccurate.
