The risk is that basically it is a dumb idea to start with -
I live in digs during the week - there were 3 of us ostensibly english guys talking about it in the kitchen the other week - we all have close family ties with scotland - I was born and raised in fife and I would not dream of going back to scotland if they split !
I have yet to find a single working jock that thinks splitting is a good idea - in fact they are unanimous that it is a crackpot thing to do - the risks are horrendous PS
