Oh my! I see the first blog has been copied on a UK site too;

Quite amazing for something that started out as a little experiment. I have made a few updates to the map and am about to post in the OP.

I'll be getting back in touch with Declan with some kind of collaboration in mind...

Thanks for posting that link - I would have never seen it otherwise!

Regards,
Lynda
