I'd agree to that Hamish, I don't see the letter itself as worth replying to but do feel it's worth pointing out that the 'idea' is already happening, and in a far more sensible way than suggested.
I also feel lads that we're reading far too much into this letter. I feel that it's just an attempt at a 'joke' at the expense of the English by someone as uninformed as he is lacking in style.
I vote that Scots and English and anyone who wants to join in invade Cornwall immediately and make Truro suffer for letting this idiot live there.
