If everywhere but Glasgow votes no, can we tell them to go it alone as a city state? 
But seriously large regional variations in the vote could be problematic.
I am not looking forward to tomorrow/today at all. But then I do have a long and unpleasant dental appointment too - so maybe it isn't all about the referendum.
DH will want to move back to England if there's a yes vote - I'll be tempted, but also curious to see how things change. But we don't really have the resources to move. If yes win, I hope they are right about everything being all right on the night (and for the next x years). Please if it does go to yes, get Gordon Brown and his contacts working on what the best solution is vis a vis the currency/debt/economy. I'm not convinced about the White Paper at all.
It's going back a bit... but with the discussion about the Greens up thread... I'm a green sympathiser... but I've been getting more and more frustrated with Patrick Harvey, who the Yes campaign has been happy to have a high profile to get the green/lefty vote, but they have been rubbish about supporting Green ideas. It got to the point that Patrick has started sounding like them on the currency union etc. It's just wrong. Keep your distinctive voice Greens.
Emotionally... I feel that Scotland hasn't really thought about what it is giving up. I was in London a couple of weeks ago (first time in years, I don't travel much) and in Devon visiting family. I loved it. I love being part of the same country. London is my capital city just as much as Edinburgh is, I'd hate to be forced to give it up. It feels like it belongs to me, our elected representatives sit there, and it's an amazing place. My sister has recently moved there to live and she loves it.
On the flag, practically I can't see it changing. The UK has had it for so long I think it will want to keep it and it's used in the corner of many other countries flags.
